Native Commands in PowerShell – A New Approach – Part 2
How to wrap native commands to take better advantage of the PowerShell environment
Native Commands in PowerShell – A New Approach
In this two part blog post I'm going to investigate how PowerShell can take better advantage of native executables. In the first post, I'm going to discuss a few of the ways that PowerShell can better incorporate native executables into our object oriented world and how we can use these tools to better fit into our model of more discrete operations. In the second post, I'll be exploring some of the work to more easily convert the use of native tools into the cmdlet/object output model of PowerShell. PowerShell provides a number of benefits to its users Some of these are not unique ...
Resolving PowerShell Module Assembly Dependency Conflicts
When writing a PowerShell module, especially a binary module (i.e. one written in a language like C# and loaded into PowerShell as an assembly/DLL), it's natural to take dependencies on other packages or libraries to provide functionality. Taking dependencies on other libraries is usually desirable for code reuse. However, PowerShell always loads assemblies into the same context, and this can present issues when a module's dependencies conflict with already-loaded DLLs, preventing two otherwise unrelated modules from being used together in the same PowerShell session. If you've been hit by this yourself, you w...
PowerShell Team May 2020 Update
Previously, I published a blog on our investments plans during the PowerShell 7.1 release timeframe. We've made progress across many of those investments with more work ahead of us.

This means that you can start leveraging new capabilities in .NET 5 and assess the new performance improvements. For PowerShell it means we can find issues early during integration with .NET and get those issues resolved much more quickly. Because we will be able to simultaneously release with .NET, it also means users will g...

Summary To provide the best-in-class encryption to our customers, the PowerShell Gallery has deprecated Transport Layer Security (TLS) versions 1.0 and 1.1 as of April 2020. The Microsoft TLS 1.0 implementation has no known security vulnerabilities. But because of the potential for future protocol downgrade attacks and other TLS vulnerabilities, we are discontinuing support for TLS 1.0 and 1.1 in the PowerShell Gallery. For information about how to remove TLS 1.0 and 1.1 dependencies, see the whitepaper Solving the TLS 1.0 problem. More information As of April 2020, TLS 1.2 is set to be the default for the...
Depending on the right PowerShell NuGet package in your .NET project
Alongside the executable packages published with each PowerShell release, the PowerShell team also maintain several NuGet packages that are available on NuGet to allow targeting PowerShell as an API platform in .NET. As a .NET application that both provides APIs and expects to load .NET libraries implementing its own (binary modules), it's essential that PowerShell be available in the form of a NuGet package. Currrently there are several NuGet packages that provide some representation of the PowerShell API surface area, and which to use with a particular project hasn't always been made clear. This blog...

(Note: we reserve the right to move this day if any significant issues arise that require us to ship an RC2.) We hope this encourages more folks...
Improvements in Windows PowerShell Container Images
Beginning with Windows Server 20H1 Insider builds, Windows Server Core Insider images have been reduced in size from ~2.1 GBs to ~1.1 GBs. How did the Server Core images get over 40% smaller? Traditionally, Windows 10 and Windows Server have always included a set of .NET native binaries that were pre-compiled using the Native Image Generator tool (Ngen.exe). This native pre-compilation makes these binaries faster on default installations of the OS, but it also makes the image size grow: managed/IL .NET binaries are typically smaller and slower initially (until JIT compilation happens) than their native coun...

PowerShell Core Release Improvements
For PowerShell Core, we basically had to build a new engineering system to build and release it. How we build it has evolved over time as we learn and our other teams have implemented features that make some tasks easier. We are finally at a state that we believe we can engineer a system that builds PowerShell Core for release with as little human interaction as necessary.
The Next Release of PowerShell – PowerShell 7
Recently, the PowerShell Team shipped the Generally Available (GA) release of PowerShell Core 6.2. Since that release, we've already begun work on the next iteration!

Parsing Text with PowerShell (3/3)
This is the third and final post in a three-part series. In the previous posts, we looked at the different operators what are available to us in PowerShell. When analyzing crashes at DICE, I noticed that some of the C++ runtime binaries where missing debug symbols. They should be available for download from Microsoft's public symbol server, and most versions were there. However, due to some process errors at DevDiv, some builds were released publicly without available debug symbols. In some cases, those missing symbols prevented us from debugging th...
Parsing Text with PowerShell (2/3)
This is the second post in a three-part series. The operator The operator splits one or more strings into substrings. The first example is a name-value pattern, which is a common parsing task. Note the usage of the Max-substrings parameter to the operator. We want to ensure that it doesn't matter if the value contains the character to split on. When the line to parse contains fields separated by a well known separator, that is never a part of the field values, we can use the operator in combination with multiple assignment to get the fields into v...

Announcing the PowerShell Preview Extension in VSCode
![Sydney Smith [MSFT]](https://secure.gravatar.com/avatar/931440e4cdbfa89ec23381a070988370?s=96&r=g){kind=avatar}
Preview builds of the PowerShell extension are now available in VSCode We are excited to announce the PowerShell Preview extension in the VSCode marketplace! The PowerShell Preview extension allows users on Windows PowerShell 5.1, Powershell 6.0, and all newer versions to get and test the latest updates to the PowerShell extension and comes with some exciting features. The PowerShell Preview extension is a substitute for the PowerShell extension so both the PowerShell extension and the PowerShell Preview extension should not be enabled at the same time. Features of the PowerShell Preview extension The PowerSh...
Parsing Text with PowerShell (1/3)
This is the first post in a three part series. A task that appears regularly in my workflow is text parsing. It may be about getting a token from a single line of text or about turning the text output of native tools into structured objects so I can leverage the power of PowerShell. I always strive to create structure as early as I can in the pipeline, so that later on I can reason about the content as properties on objects instead of as text at some offset in a string. This also helps with sorting, since the properties can have their correct type, so that n...
Windows Security change affecting PowerShell
Windows Security change affecting PowerShell January 9, 2019 The recent (1/8/2019) Windows security patch CVE-2019-0543, has introduced a breaking change for a PowerShell remoting scenario. It is a narrowly scoped scenario that should have low impact for most users. The breaking change only affects local loopback remoting, which is a PowerShell remote connection made back to the same machine, while using non-Administrator credentials. PowerShell remoting endpoints do not allow access to non-Administrator accounts by default. However, it is possible to modify endpoint configurations, or create new cust...

PowerShell Constrained Language mode and the Dot-Source Operator
PowerShell Constrained Language mode and the Dot-Source Operator PowerShell works with application control systems, such as AppLocker and Windows Defender Application Control (WDAC), by automatically running in ConstrainedLanguage mode. ConstrainedLanguage mode restricts some exploitable aspects of PowerShell while still giving you a rich shell to run commands and scripts in. This is different from usual application white listing rules, where an application is either allowed to run or not. But there are times when the full power of PowerShell is needed, so we allow script files to run in FullLanguage mode ...
Announcing General Availability of the Windows Compatibility Module 1.0.0

PowerShell Module Function Export in Constrained Language
PowerShell Module Exporting Functions in Constrained Language PowerShell offers a number of ways to expose functions in a script module. But some options have serious performance or security drawbacks. In this blog I describe these issues and provide simple guidance for creating performant and secure script modules. Look for a module soon in PSGallery that helps you update your modules to be compliant with this guidance. When PowerShell is running in Constrained Language mode it adds some restrictions in how module functions can be exported. Normally, when PowerShell is not running in Constrained Language, all ...
PowerShell Standard Library: Build single module that works across Windows PowerShell and PowerShell Core
This is the first of a series of blog posts that will help you take advantage of a new NuGet package PowerShellStandard Library 5.1.0. This package allows developers to create modules that are portable between Windows PowerShell 5.1 and PowerShell Core 6.0. This means that you can create PowerShell modules that run on Windows, Linux, and macOS with a single binary! The version of PowerShell Standard Library indicates the lowest version of PowerShell that it is compatible with. The community promise is that it is always forward compatible. So a module built against PowerShell Standard Library v3 is compatible w...
PowerShell Injection Hunter: Security Auditing for PowerShell Scripts
At the DEFCON security conference last year, we presented the session: "<a href="https://www.youtube.com/watch?v=ahxMOAAani8">Get $pwnd: Attacking Battle Hardened Windows Server</a>". In this talk, we went through some of the incredibly powerful ways that administrators can secure their high-value systems (for example, Just Enough Administration) and also dove into some of the mistakes that administrators sometimes make when exposing their PowerShell code to an attacker. The most common form of mistake is script injection, where a script author takes a parameter value (supplied by an attacker) and runs it in a...
Increased Windows Modules coverage with PowerShell Core 6.1
During the May 2018 Community Call and a tweet a few weeks later, we mentioned that PowerShell team was spending significant time in the Windows codebase. We even demoed using the Active Directory PowerShell Module from PowerShell Core 6 during the PowerShell Community Call. We started investigating some of the top requested modules that ship with Windows to see how to get them working in PowerShell Core 6. Our eventual goal is to have near 100% parity with Windows PowerShell for the in-box modules, but we expect this effort to span across multiple releases of Windows as there are many modules and PowerShell tea...

In addition there are community projects to build solutions for DSC entirely driven by the community, such as Datum to manage configuration data at scale, BaselineManagement to...
Prerelease Versioning Added to PowerShellGet and PowerShell Gallery
With the release of PowerShellGet 1.6.0, PowerShellGet cmdlets and the PowerShell Gallery have added support for prerelease strings for prerelease versions of modules and scripts. You can now publish items to the PowerShell Gallery with a version like 1.0.0-alpha, and you can download items identified as a prerelease. Items can be filtered using prerelease version strings, in both the Gallery UI and via Find-* cmdlets. Before this feature, if publishers wished to publish a prerelease version of an item, they had to use a version lower than 1.0.0 (ex. 0.0.1). This meant it was not possible to publish a prerelea...

Azure Automation DSC Pricing Flexibility
Today we would like to share a new flexible pricing strategy for managing server nodes using Azure Automation to deliver PowerShell Desired State Configuration, giving you greater control over costs of managing on-premises nodes. As you might already know, Azure Automation DSC (Azure DSC) is a managed service that is free when used to manage virtual machines running in Microsoft Azure. This provides the functionality of the in-box DSC Pull server without needing to maintain a server to host the capability, plus a lot of additional features. Some of the goodies that you get with Azure DSC are as follows: Fea...
PowerShell Constrained Language Mode
PowerShell Constrained Language Mode Update (May 17, 2018) In addition to the constraints listed in this article, system wide Constrained Language mode now also disables the ScheduledJob module. The ScheduledJob feature uses Dot Net serialization that is vulnerable to deserialization attacks. So now whenever an application whitelisting solution is applied such as DeviceGuard or AppLocker, PowerShell will run in Constrained Language mode and also disable the ScheduledJob module. Use the Windows Task Scheduler or PowerShell ScheduledTasks module as an alternative. For more information see CVE-2018-0958. What i...
Defending Against PowerShell Attacks
[Updated Feb 20th, 2020 with latest guidance] The security industry is ablaze with news about how PowerShell is being used by both commodity malware and attackers alike. Surely there’s got to be a way to defend yourself against these attacks! There absolutely is. PowerShell is - by far - the most securable and security-transparent shell, scripting language, or programming language available. Our recommendations are: Some security professionals recommend disabling PowerShell as a method of risk mitigation. Microsoft’s guidance on this falls into two areas: For further...
Require License Acceptance Support in PowerShellGet
![Fareha Rashid[MSFT]](https://devblogs.microsoft.com/powershell/wp-content/uploads/sites/30/letter-avatar/2b6f33b7bd531694a9cdd4ff71e67c7c.svg){kind=avatar}
PowerShellGet version 1.5.0 has added support for module publishers to require explicit license acceptance from users before installing a module. This feature has been requested by several of our partners, in order to meet their legal requirements. If a user installs, updates, or saves a module using PowerShellGet, and the publisher of that module requires the user to agree to a license, the user must indicate they accept the license or the operation fails. This works whether the module is installed directly or if it is installed because it is a dependency for another module. Publishing Requirements for Modules...

Windows PowerShell 2.0 Deprecation
We recently announced that Windows PowerShell 2.0 is being deprecated in the Windows 10 Fall Creators Update. Deprecation is a process whereby technologies or applications are marked as legacy, signalling to users that they may be removed in the future, and that should move away from them and towards newer alternatives. We do not currently have a timeline to remove Windows PowerShell 2.0, but as we continue to evaluate its usage in the PowerShell ecosystem, we will be working to remove it in a future release. When this decision is made, we will give plenty of notice via official Windows deprecation channel...

PowerShell 6.0 Roadmap: CoreCLR, Backwards Compatibility, and More!
As we've made progress on open-source PowerShell, it's time to start talking more in-depth about: PowerShell Editions There are two editions of PowerShell: Windows PowerShell is the edition of PowerShell built on top of .NET Framework (sometimes referred to colloquially as "FullCLR"): PowerShell Core is the edition of PowerShell built on top of .NET Core (sometimes simplified to "CoreCLR", though it technically includes CoreFX as well). Note: while PowerShell Core 6.0 is cross-platform, there is also a PowerShell Core 5.0/5.1 released exclusively as part of Nano Server. Com...

OpenSSH Security Testing Kick Off
Over the past while, we’ve been very busy porting OpenSSH to Win32. We’ve been working with the OpenSSH community in our GitHub repository, and are nearing a point where we are taking steps to make it production ready. Security is obviously something that we have focused on during every phase of the project. As part of this production readiness phase, however, we are additionally funding an extensive penetration test. We have engaged Casaba Security as part of this effort, who will be digging deep into the implementation over the next 1-2 months. As with all aspects of this project, one of our main goals is t...
DSC Configuration Sharing
The community around DSC Resources has been inspiring. The PowerShell Gallery now includes more than 2000 modules/scripts. 181 of those are modules focused on DSC, that collectively include 766 DSC Resources. With this many building blocks available, it has become easier and faster to get a DSC project through the proof of concept phase to production-ready Windows Servers built using Configuration As Code. When the author is new to DSC, their first configuration is a complex learning experience. The modules containing DSC Resources often have an /Examples folder with Configuration scripts showing how to use...

A Comparison of Shell and Scripting Language Security
PowerShell Security is a topic on everybody's mind. Most of all - ours. As PowerShell has become more popular with Administrators, it has also become more popular for unauthorized administrators - also known as "Attackers". In any operating system or platform, the power and efficiency you provide to authorized administrators is also available to unauthorized administrators. For example, Unix, Linux, and Mac all have dozens of powerful built in compilers, scripting languages, and debuggers. It's a power user's dream, but also a liability. The PowerShell team has recognized this double-edged sword since the intro...

Using PowerShell Modules in Azure Functions
Previously, I blogged about how I created PowerShell GitHub Dashboard using Azure Functions to run a PowerShell script and didn't use PowerShell Modules as I didn't find an easy way to do it with Azure Functions. Stefan informed me that you can easily do it using FTP! Today, I'm publishing a guest blog post that Stefan authored that walks you through how to use PowerShell Modules in Azure Functions! Steve Lee published a couple of blog posts about how he created a PowerShell Open Source Community Dashboard in PowerBi. In his last blog post he explained how he used PowerShell, Azure StorageTable, Azur...
Code Coverage – Part 2
In my last post on code coverage, I shared the process for you to collect coverage for your environment. This week, I'll be describing a way to use our tools to create new tests and show how you can measure the increase of coverage for PowerShell Core after adding new tests. To recap, we can collect code coverage with the OpenCover module, and then inspect the coverage. In this case I would like to know about coverage for a specific cmdlet. For this post, we're going to focus on the Clear-Content Cmdlet because coverage is ok, but not fantastic and it is small enough to go over easily. Here's a partial capture f...
Managing Security Settings on Nano Server with DSC

Building a GitHub Dashboard using PowerShell, AzureStorageTable, AzureFunction, and PowerBI
Last week, I published a PowerShell Community Dashboard and today, I'm going to share the code and cover some of the learnings.The code is published as a module on the PowerShell Gallery. Make sure you get v1.1 as I found an issue where if you're not a member of the PowerShell Org on GitHub, you won't have permission to query the members so I changed the code to accommodate that.You can install the module using: (and it works on PowerShell Core 6.0 including Linux! I only tested it with alpha.15, though...) Once installed, you can just run it manually: The is something you would gener...

Install PowerShell Core on Ubuntu 14.04 Install PowerShell Core on Ubuntu 16.04 Install PowerShell Core on CentOS After registering the Microsoft repository once as supe...
PowerShell Open Source Community Dashboard
Since going cross-platform and open source on GitHub, I've wanted to know how we are doing as a community and who the top contributors we should recognize are. The available GitHub graphs are not sufficient as they focus on commits, and there are many other ways for the community to contribute to PowerShell. Certainly receiving Pull Requests (PRs) has a direct impact on the code base, but opening issues, commenting on issues, and commenting on PRs (aka code reviews) are also immensely appreciated and valuable to help improve PowerShell.In addition, PowerShell is not a single repository, but several repositories t...

Tips and Tricks from PowerShell Core Validation
It has been a privilege for the CAT team to work with customers and the PowerShell team to validate early builds and experiences with PowerShell Core. Some of the customers involved were key influences on the whitepaper, The Release Pipeline Model Applied to Windows Server and Microsoft Cloud. As a result, validation has included many experiences from outside the traditional Microsoft tool chain, such as Vagrant and Jenkins. For this blog post, I wanted to share some of the learnings that I gained during the validation experience. This is not meant to be a complete picture of PowerShell Core. Rather, a glimpse...

PowerShell Security at DerbyCon
Many people have commented over the past couple of years that they’d love to see a PowerShell Security conference. Well, that conference arrived: DerbyCon 2016. DerbyCon is an incredible security conference, held in Louisville Kentucky each year. Despite the calibre of all that attend, the humbleness and approachability of everyone there is outstanding. Perhaps to a fault. It’s only after talking to somebody and looking them up on Twitter do you realize it’s THAT person, and openly wonder if asking for an autograph would have been too awkward. It’s probably best to stop talking about how great of a conference i...

PowerShell DSC and implicit remoting broken in KB3176934
On August 23, Windows update KB3176934 released for Windows Client. Due to a missing .MOF file in the build package, the update breaks DSC. All DSC operations will result in an “Invalid Property” error. In addition, due to a missing binary in the build package the update breaks PowerShell implicit remoting. Implicit remoting is a PowerShell feature where PowerShell commands work on a remote session instead of locally. Specifically, importing a remote session no longer works: $remoteSession = New-PSSession -Cn TargetComputer Import-PSSession -Session $remoteSession Import-PSSession : Could not load type 'System.M...
PowerShell on Linux and Open Source!
Since its inception in 2002 PowerShell has been deeply influenced and improved by the passion and needs of our community. As an example, 80 contributors filed bugs and issues on the “alpha” release.

DSC Resource Kit – Anniversary Release
We've just updated the DSC Resource Kit to celebrate our 1 year open-source anniversary! The DSC Resource Kit has come a long way in a year. Originally, DSC started with only in-box resources. To make these resources easier to update, some were moved to TechNet's Script Center and became the DSC Resource Kit. Finally in April 2015, the DSC Resource Kit was open-sourced to the community on GitHub with all modules available to download in the PowerShell Gallery. Now, the DSC Resource Kit has passed it's first anniversary as open-source, and what a year it's been! We now have 302 DSC Resources across 52 modules!...
New Security Cmdlets in Nano Server
In Windows Server 2016 TP5, we included two new cmdlets to help manage security policy settings. While they are present on every install option of Windows Server, these are mostly useful on Nano Server because Nano Server does not support Group Policy. Security-related settings include two different kinds of artifacts. • .INF files containing security policy template settings. These are handled by the "securityCmdlets"(*) module that ships in Technical Preview 5 • .CSV files containing advanced audit settings. these are handled by the "securityCmdlets"(*) module that ships in Technical Preview ...

This preview installs exclusively on systems running PowerShell 4 or PowerShell 3 only. This preview will not instal...
Announcing the Underhanded PowerShell Contest
In an effort to improve the validation capability of PowerShell Script Analyzer, we are running a series of contests. We want you - the community members - to help us identify underhanded PowerShell scripts, and then create rules to catch them. There are specific areas where Script Analyzer rules are needed and we need your skills to help us hone them. What is underhanded PowerShell code? Basically, code that is designed to do something the user would not intend, or takes actions that are not apparent to someone who would casually read the code. For example, an underhanded approach to running ‘[System.Runtime.Int...

ScriptAnalyzer v1.2.0 Released
Improving the PowerShell feedback experience with UserVoice
Since the early days of PowerShell 1.0, the PowerShell Team has been using Connect to manage customer feedback, feature requests, and bug reports, enabling us to have a continued pulse on the needs of the PowerShell community. However, in responding to your feedback, we also realize that Connect is starting to show its age and that our cloud cadence demands a feedback platform that drives rapid and direct engagement with the PowerShell Team. Starting today, we're joining the rest of Windows Server by opening the doors on the PowerShell forum within the Windows Server UserVoice. The move to UserVoice will allow u...
PowerShell Tests released on GitHub
The PowerShell team is excited to make its first release of our test code on GitHub. This project represents a selection of tests that the PowerShell team uses when testing PowerShell. In the more than 12 years of active development on PowerShell, we have created (and continue to use) many different script based test frameworks. As part of an effort to simplify our test infrastructure, early in 2015 we started the migration process of our internal script based framework tests to the Pester (https://github.com/pester/Pester) framework; the release of this project represents the early fruits of that labor. Our plan...

PowerShell Language Design – Request for Comments
For a while now, we've been thinking about how to better incorporate the community into the PowerShell language design process. We believe this would improve PowerShell by: A Request for Comments (RFC) is a type of document used broadly in the industry, in various forms, as a way to collect feedback from customers and partners. We are adopting this concept as a way to get feedback on language design documents. This is something that is new to us, so we are starting smal...
Announcing PowerShell language support for Visual Studio Code and more!

Write and debug PowerShell scripts in Visual Studio Code! The first release is a new extension for Visual Studio Code which provides improved PowerShell language support including IntelliSense, code navigation, real-time script analysis, and local script debugging. Previous releases of Visual Studio Code have provided basic PowerShell syntax highlighting support and code snippets. This summer I started working with a PowerShell team intern,&...
Compromising Yourself with WinRM’s “AllowUnencrypted = True”
One thing that’s a mixed blessing in the world of automation is how often people freely share snippets of code that you can copy and paste to make things work. Sometimes, this is a snippet of code / functionality that would have been hard or impossible to write yourself, and saves the day. Sometimes, this is a snippet that changes some configuration settings to finally make something work. For both types of code, you should really understand what’s happening before you run it. Configuration snippets are particularly important in this regard, as they permanently change the posture of the system. One disappointi...
Azure DSC Extension – Versions 1.0-2.3 no longer available
NOTE: For information on OS support, and other features, please refer to our release history. Today we retired versions 1.0 to 2.3 of the Azure DSC Extension. These versions use preview versions of WMF 5.0 whose signing certificates have expired, so it is no longer possible to install them. If any of these versions are already installed on your VMs they will continue to run, but you will not be able to install them on new VMs. Our PowerShell cmdlet, Set-AzureVMDscExtension still uses version 1.* as the default; you can install a different version with the –Version parameter: Starting with the soon-to-be-rel...

OpenSSH for Windows Update
Back in June, we announced our intentions to bring SSH to Windows by supporting and contributing to the OpenSSH community. Our objective was to not only port OpenSSH so that it worked well on Windows, but to openly contribute those changes back into the portable version of OpenSSH. Of the many options available, one clearly stood out: the previous work that NoMachine had already published in bringing OpenSSH to Windows. The NoMachine port was based on OpenSSH 5.9, so we’ve spent the time since our initial announcement working with NoMachine to bring this port in sync with OpenSSH 7.1. ...

Desired State Configuration + Puppet
Our goal with PowerShell Desired State Configuration is to make Windows easy to manage, regardless of what tool you’re using. We view DSC as a platform technology to manage Windows, and this technology can be extended with the creation of new resources as well as the reuse of PowerShell DSC functionality in different solutions. As Microsoft partners make their components configurable via DSC, their customers will be able to choose from a wide range of configuration management tools that support DSC. To that end, we are pleased to share that Puppet Labs has launched their support for PowerShell Desired Stat...
The New Home of DSC Documentation
I’m pleased to announce that our official PowerShell Desired State Configuration (DSC) documentation now has a new home on MSDN. We heard your feedback loud and clear, and began working on a documentation platform that reflects our customer-focused approach to addressing that feedback with improvements to the content and structure of the DSC documentation. These changes were enabled and continue to be driven by the fact that this documentation is now available in Markdown format on GitHub via the PowerShell-Docs repository. Furthermore, we have leveraged a continuous integration and deployment system to all...

Today's blog post is by guest author Mr. Ashley McGlone, also known as GoateePFE. Ashley is a Microsoft Premier Field Engineer who teaches and supports PowerShell for Microsoft Premier customers. You can find more content from Ashley at his blog on TechNet. Certificates, Oh No! One of the most common questions I get regarding PowerShell Desired State Configuration is about certificates. What kind do I need? How many? Where do they go? Most people enjoy working with certificates as much as they enjoy going to the dentist. Exactly. Many of us only touch the certificate server when we have no other choice. It i...

PowerShell Gallery – New Security Scan
Quality and trust of PowerShell Gallery content have been a concern since the beginning. These issues were somewhat addressed with peer-monitoring via the Report Abuse and Contact Support links on each module details page. We even implemented a new cmdlet, Save-Module, which allowed users to assess a module’s contents before installing it. However, all these scenarios put the onus on the consumer to determine if a module is safe and of high quality. To improve further, we have begun checking that all modules on the Gallery meet a basic quality bar. Starting June 26, 2015, all modules i...

Validate PowerShell DSC Debug
This is part five of a blog series introduced in Validate the new features of PowerShell DSC. New Capability DSC has a new debugging mode that helps with troubleshooting by making it possible to interact with scripts being run by DSC, as they are being applied. When this mode is enabled, as the machine applies the configuration, progress will stop at the first script action to wait for a remote connection to open. Once connected, the person doing the troubleshooting can interact with the session as well as use breakpoints to debug. What is the purpose of this feature? Customers have requested ad...
Validate PowerShell DSC WaitFor
This post is part four of a blog series introduced here: Validate the new features of PowerShell DSC. New Capability WaitFor is a new set of built-in configuration resources. Including the WaitFor resources in a configuration tells the configuration target machine that it should communicate with the Local Configuration Manager on a remote machine to verify that the remote has returned success, before the target machine continues its deployment. The WaitFor resources need to know which nodes to check, which DSC resource must complete successfully, how often to check, and how long to wait between checks. W...
Validate PowerShell DSC Partial Configurations
This post is part three of a blog series introduced in Validate the new features of PowerShell DSC. New Capability DSC now has the ability to merge partial configurations into one configuration for management. What is the purpose of this feature? Customers have told us that in some cases, multiple teams contribute to a configuration. It can be organizationally challenging to manage a collective configuration. Customers want to be able to allow individual teams to author the portions of the configuration for which they are responsible, and then use the DSC Local Configuration Ma...
Registration is Now Open to Publish on PowerShell Gallery
We are excited to announce that, as of today, the PowerShell Gallery will accept registration from any users who wish to publish PowerShell modules and share their work with the world. For the past year, the PowerShell Gallery has been slowly adding content from our closest community contributors, most of whom are Most Valuable Professionals (MVPs) and internal Microsoft contributors. While we were building the basic features of the PowerShell Gallery, we restricted the set of people who could publish new modules, and required an approval step before allowing users to register. This approach provided the PowerShe...
Validate PowerShell DSC Node Status
This is part of a blog series first referenced here: Validate the new features of PowerShell DSC New Capability A new cmdlet is available named Get-DscConfigurationStatus. This cmdlet returns detailed information about the status of a node. What is the purpose of this feature? Customers have told us that they need to be able to get more information about the state of a machine that is managed using DSC. In response, we have introduced a new cmdlet that is meant to begin addressing the issue. What is the easiest way to test it? You can run just the cmdlet with no special settings for basic information, o...
Validate PowerShell DSC RunAsCredential
This is the first part of a blog series originally referenced here. - Validate the new features of PowerShell DSC New Capability A new property, PSDSCRunAsCredential, is now available to specify a user credential that should be used to execute all work performed by a DSC resource. This capability is being introduced as a common property that can be used even for existing resources. What is the purpose of this feature? PowerShell DSC by default executes in the context of the machine System account, LocalSystem. That works well for the most part but there are cases where execution needs to occu...
Validate features of PowerShell DSC
As many readers of the PowerShell blog already know, the next version of PowerShell is currently in preview. It is available in the Windows Management Framework 5 Preview. You can install this package on Windows 7, Server 2008 R2, or later. Your feedback is important to us! After software ships, it is harder to introduce changes. There is a risk that any change could break something for customers who are using the current codebase. If you can get feedback while in preview it is usually easier to make changes. For this reason we are asking anyone who can take a moment to validate new features and functionality, ...
Use DSC to manage WMI namespace security
Almost 6 years ago, I wrote some PowerShell scripts in a multi-part series explaining WMI namespace security and also how to manage them using PowerShell. If you're not familiar with WMI namespace security, I recommend reading the blog posts above or even as a refresher. I received some feedback fairly recently about some issues and this presented itself as an opportunity for me to revisit this topic, but rewrite it as a DSC resource using the new PowerShell Classes syntax. Since I'm using PowerShell classes, you'll need either Windows 10, Windows Server 2016 Preview, or Windows Management Framework 5.0 install...
DSC Resource Kit flourishes as open source
We are excited to announce the recent updates which were made to DSC Resource Kit since open sourcing it on GitHub! We were working hard on improving coverage and robustness of DSC as well as saw incredible engagement from the community in the recent months. That effort resulted in adding 32 new DSC resources across 8 modules and fixing bugs in 22 resources across 17 modules since last release at the beginning of May! It means that we’ve achieved our next milestone of 200 resources and are now up to a total of 212 DSC resources! For those who love numbers as much as we do, here’s couple other statist...
Want to write a DSC resource where only a single instance can be configured?
I've heard from a few DSC resource authors that they need a method to implement a resource that has a single instance; a singleton. The problem they encountered is a DSC resource must define a Key property but singleton resources generally should not have a key because there is only one instance that can be updated. The problem can been seen by examining the xTimeZone and xRemoteDesktopAdmin resources. xTimeZone configures the system's current time zone and uses the time zone as the key. The problem is this would let you specify the time zone multiple times during your configuration even though there is on...
Azure DSC Extension v2.0 released
NOTE: For information on OS support, and other features, please refer to our release history. Today we are releasing version 2.0 of the Azure DSC Extension, with improvements for DSC configurations that reboot the VM, and fixes for ARM deployments. We are releasing this version as a major version change, instead of a minor revision, because you may need to modify your DSC configuration in order to use this release. The changes in this release might affect you if Otherwise, the Extension should have the same behavior as in previous versions and you should have no problem continuing to use the same DSC config...
PowerShell ♥ the Blue Team
(Warning: Long blog post ahead! If you’d like to read (or share) this as a whitepaper, you can download it here: “Scripting Security and Protection Advances in Windows 10”). At Microsoft, we invest an enormous amount of time and energy managing world-class cloud services and incredibly large enterprise networks. Security is critical for all of these – so what might surprise you is that we also invest enormous amounts of time and energy trying to break into those services. This is called Red Teaming – taking highly specialized groups of security experts and having them adopt the role of sophisticated adversaries...
Looking Forward: Microsoft Support for Secure Shell (SSH)
[UPDATE]: Read more about our detailed plans, roadmap, and where you can play with the in-progress code here. As Microsoft has shifted towards a more customer-oriented culture, Microsoft engineers are using social networks, tech communities and direct customer feedback as an integral part on how we make decisions about future investments. A popular request the PowerShell team has received is to use Secure Shell protocol and Shell session (aka SSH) to interoperate between Windows and Linux – both Linux connecting to and managing Windows via SSH and, vice versa, Windows connecting to and managing Linux via SSH. ...
How to register a node with a DSC pull server
NOTE - The latest information regarding DSC Pull Service can be found in the DSC documentation using the link: https://docs.microsoft.com/en-us/powershell/dsc/pullserver .......... In PowerShell 4.0, each node in a DSC configuration identifies itself to the pull server with its ConfigurationId, a GUID. In the case of pull mode (where a node downloads the configuration from a pull server), this ConfigurationId also maps to the name of the configuration document (the MOF file) stored on the pull server (you can read more about pull vs. push modes in this blog). As the configuration document’s name is a GUID and ...
Azure PowerShell DSC Extension v1.10 released
NOTE: You can find more information on the DSC Extension in our release history. Today we released a minor update to the Azure DSC Extension: version 1.10.1.0. This update addresses a couple of issues that were producing false error messages on some ARM deployments. Please feel free to give us your feedback as comments to this post, or using Connect: https://connect.microsoft.com/PowerShell/Feedback.
Update JEA for the April WMF 5.0 Preview
This year, at the Ignite Conference, we presented Just Enough Administration (JEA), a PowerShell toolkit for granularly managing administrator privileges. Older versions of JEA do not work with the recently released April WMF 5.0 Preview. This is due to an issue with WinRM when registering a new endpoint. The latest version (0.2.16.6) of JEA contains a workaround, and is available in the PowerShell Gallery. Please install this version of the module to use JEA with the April WMF 5.0 Preview. If you are updating an existing system with JEA to the April WMF 5.0 Preview, please take the...

Desired State Configuration Resources for PackageManagement Providers
Introduction You may have heard of, or even already used PackageManagement (aka OneGet). Recently, I was reading the OneGet blog and OneGet in GitHub, and decided to give it a try by installing the Windows Management Framework (WMF) 5.0 Preview April 2015. I found that PackageManagement provides a consistent user experience by exposing the same set of PowerShell Cmdlets for different flavors of software installation technologies, such as PowerShell modules, NuGet packages, MSI, MSU, etc. It’s indeed a unified package management framework. So I decided to write some Desired State Configuration (DSC) resource...

DSC Resource Kit Moved to GitHub
We are proud to announce that the entire DSC Resource Kit has been open-sourced on GitHub. This means that we will be iterating and releasing these DSC resources quicker than ever before. It also means that we will be collaborating more openly with the community by accepting GitHub pull requests into our code. For those of you who just want to consume the resources: we will no longer be publishing updates to the DSC Resource Kit resources on TechNet. Instead, we will publishing new updates directly to the PowerShell Gallery where they can be downloaded using PowerShellGet (which is now a...
PowerShell Tools for Visual Studio – Now Available
A few days ago Jason Helmick asked Jeffery Snover on the MCP Insider Series when we’d see PowerShell in Visual Studio. That actually wasn’t the first time the question had been asked. Well, here’s the answer… Today at the PowerShell Summit North America 2015, Andre Sayre gave a demo of PowerShell Tools for Visual Studio, an extension for Visual Studio that provides edit, run and debug capabilities for PowerShell scripts and modules in the Visual Studio IDE. Over the past few months we (at Microsoft) have been working with Adam Driscoll, a Microsoft MVP who sta...
Community Feedback and Microsoft Connect
Community feedback is an integral part of any software development cycle. That's why we continue to release new preview versions of Windows Management Framework (WMF) 5.0: so that we can hear about and fix real-world problems before they ship with the next version of Windows. Historically, our guidance for filing bugs and feature requests, for both WMF5 and previous versions of PowerShell, has been to use our Microsoft Connect page. Our ability to pick up and address issues on Connect has varied throughout the life of PowerShell. As Microsoft has shifted towards a more customer-oriented culture, we have...
Introducing Get-AzureVMDscExtensionStatus cmdlet for Azure Powershell DSC Extension

Invoking PowerShell DSC Resources directly
PowerShell Desired State Configuration (DSC) is a distributed Configuration Management (CM) platform which delivers a uniform way to configure Windows components. Configuration Management tools should layer on top of DSC and components in the Windows server ecosystem should write DSC providers to ensure that customers can choose any CM tool they want and be confident that it will be able to configure every resource they use. Just as you don’t investigate what printers a word processor supports before you buy it, you shouldn’t have to check what resources a CM tool supports before you buy ...

Securely allocating GUIDs in PowerShell Desired State Configuration Pull Mode
Nicholas Dille recently posted a good blog on GUID management in PowerShell Desired State Configuration. In that blog, he goes through several approaches to GUID management and talks about the pros and cons of each. When you are deciding how to allocate GUIDs in DSC’s Pull Mode here are the three things you should keep in mind: When we designed this feature, we initially wanted to use the computer / SMBIOS GUID for this identifier and be done with it. However these GUIDs are not generally treated as sensitive data. They get littered in event logs everywhere, fly across the network unencrypted duri...
Another Holiday Present From the PowerShell Team – DSC Reskit Wave 9
Here’s a holiday gift from the PowerShell team – the DSC Resource Kit wave 9. You can find it right here. This wave has something for everyone, we hope. There are 34 new DSC resources across 13 modules! We have also incorporated your feedback, and made fixes to several existing resources that address issues you have encountered. Last year we delivered the first DSC Resource Kit as a holiday gift, with 11 DSC resources. In case you are counting, we now have 172 DSC resources, enabling use of DSC for deploying and configuring Active Directory, Azure VMs, Certificate Services, SQL Server, DNS, file share...
Tower of Power – December 2014 Update
You may remember Jeffrey posting about the "Tower of Power" in 2008: http://blogs.msdn.com/b/powershell/archive/2008/03/27/tower-of-power-part-2.aspx. For curiosity, I was just doing a little investigation on the number of PowerShell books available, and the number has grown somewhat. I did some web scraping of Amazon for anything with ‘PowerShell’ in the title, and manually attempted to remove duplicates (although kept multiple editions as their own entry). Quite the selection! Active Directory with PowerShell Automating Active Directory Administration with Window...
PowerShell Job Debugging
This is the third of a series of blogs discussing the new PowerShell 5.0 script debugging features. These new features are available through the PowerShell 5.0 preview, which is part of the WMF (Windows Management Foundation) 5.0 preview that you can get from HERE. In my first article I talked about the script debugger Break All command. Here I will discuss the new Debug-Job Cmdlet. In a way the Debug-Job Cmdlet is really just a Break All command for PowerShell jobs. Recall that jobs are PowerShell’s way to run script asynchronously. Normally you don’t run scripts as jobs...
WMF 5.0 Preview: Defining “experimental designs” and “stable designs”
Over the recent releases of Windows Management Framework 5.0 Preview (find the latest here), we’ve distributed some new functionality and heard some wonderful feedback. As we improve on these features and as more users start to use Windows Management Framework 5.0 Preview, we feel the need to make a distinction in the functionality delivered. The distinction we expect will be most useful is “can I use this code in production?” So we’re marking different scenarios and features in our release notes as having “experimental designs” or “stable designs”. The goal of feat...
PowerShell DSC Azure Extension 1.5 is now available
We’re excited to announce version 1.5 of the Azure DSC extension, which now supports Windows Server 2012 (in addition to Windows Server 2012 R2). Version 1.5 uses the Windows Management Framework 5.0 Preview November 2014. You can see the history for previous releases in this post.

See our blog post for more information. Version 2.70 - 2.72 Versi...
PowerShell Remote Script Debugging in the ISE
This is the second of a series of blogs discussing the new PowerShell 5.0 script debugging features. These new features are available through the PowerShell 5.0 preview, which is part of the WMF (Windows Management Foundation) 5.0 preview that you can get from HERE. In this blog I will discuss the new features that support remote script debugging in the PowerShell ISE (Integrated Script Environment). Remote script debugging support was added to PowerShell 4.0 but only for the PowerShell console and not the ISE. We have rectified this for PowerShell 5.0 and have also added the ability to open, ed...
PowerShell Break All Command
The PowerShell team has added some new script debugging features for version 5.0. I’ll be talking about these new features in a series of blogs starting with the new PowerShell Break All command. PowerShell 5.0 has been released as a preview over the last few months. While PowerShell is in preview new features are continually evolving so if you want to try them out you should ensure you have the latest preview version. The script debugging features I’ll be discussing require the latest preview release which at this writing is the November 2014 release. You can down load P...
Introducing: PowerShell Gallery
PowerShellGet is an exciting new feature releasing in WMF 5.0 Preview. With it, you can easily discover, install, update, and publish PowerShell modules to and from online repositories – simplifying the process of sharing PowerShell content. While we’ve talked about how to set up your own repository in the past, we haven’t said much about PowerShellGet’s default Gallery. When you run Find-Module, you may have noticed that it automatically searches a “PSGallery” repository. You may have wondered, “what exactly is this PSGallery repository?" Today, we are ...
Documenting DSC Part 2
In a previous post, we introduced the team of writers working on documenting DSC. (You can always contact them at DSCIX@microsoft.com.) We’ve started out by bringing the existing documentation up to date (the topics for all of the built-in resources have been brought current, for example) and transferring all or parts of most of the posts in this blog concerning DSC into the Technical Library. For your reference, here’s a table that relates the DSC blog posts to the corresponding Technical Library articles:

Jaime – I’m 14-year veteran of Microsoft. At one time I was a tester in Exchange, bu...
ConvertFrom-String: Example-based text parsing
Intro I’m sure most of you are familiar with the powerful tools for text parsing available in PowerShell. A presentation at the PowerShell Summit a couple of weeks ago provides a good overview of these and mentions a new Powershell cmdlet, ConvertFrom-String, that was introduced in Windows Management Framework 5.0 Preview September 2014. ConvertFrom-String lets you parse a file by providing a template that contains examples of the desired output data rather than by writing a (potentially complex) script. A Simple Example The namesAndCities.input.txt attached to this po...

Simple HTTP api for Executing PowerShell Scripts
[Based on the feedback, I've renamed this to HTTP] There may be scenarios where you don’t need the full interactive experience of PowerShell remoting over PSRP (PowerShell Remoting Protocol), or have the need to execute some PowerShell scripts from a non-Windows system. You could directly code against WS-Man as I’ve blogged about a long time ago, however, it’s quite complicated requiring knowledge of SOAP and WS-Man. In cases where you want to simply invoke a PowerShell script remotely, a REST api is a good choice since all modern programming languages make it simple to perform...

Creating a Secure Environment using PowerShell Desired State Configuration
Introduction: Traditionally, IT environments have secured their business critical information against external threats by adding additional layers of security to the org’s network (e.g. firewalls, DMZs, etc.). However many of today’s attacks are coming from inside the network so a new “assume breach” approach must be adopted. In this blog, we show how to create a secure environment to run a particular application or service inside of an assume-breached network. This substantially reduces the attack surface of the application or service by configuring a highly customized, application specific environment, by...

At TechEd, we announced and released an early version of PowerShellGet: a package manager for PowerShell modules. The response was positive, and many people asked the same type of question: “Can I set up my own internal repository for PowerShellGet?” Many enterprise-oriented houses want the ability to create private module repositories (without sharing them with the world). Many security minded folks want to curate their own module collections. The short answer to this question is: yes! All you need to do is create your own NuGet Server and redefine a couple of ...
Announcing Windows PowerShell Desired State Configuration for Linux
For those of you fortunate enough to be at TechEd North America last week, you might have seen Jeffrey Snover announcing Windows PowerShell Desired State Configuration (DSC) for Linux! (If you missed that session, you can watch a replay of it online). We are excited to announce the initial availability of this feature with the release of a CTP of DSC for Linux at GitHub.com. With DSC for Linux, you can now use the same platform to concurrently manage the configuration of your Windows and Linux computers. We are actively developing DSC for Linux and will continue to improve and extend it going forward. Bring...

Understanding Import-DscResource Keyword in Desired State Configuration
Desired State Configuration resources are used to model and change the state of different components of the system. In an earlier blog post, we discussed details about deploying and discovering those resources and introduced Import-DscResource dynamic keyword. In this post, we will discuss some more details about the usage and internal working of this dynamic keyword. This keyword is only available inside configuration block. Its syntax looks like PowerShell cmdlet but it’s not a cmdlet and behaves differently. When authoring the DSC configuration in ISE, the PowerShell parser, pro...
Debug Mode in Desired State Configuration
The DSC engine caches resources implemented as a PowerShell module for efficiency purposes. This can sometimes turn out to be annoying, when you are authoring a resource and testing it simultaneously. The only way to cause DSC to load the newer version every time is to explicitly kill the process hosting the DSC engine. As part of the WMF5 CTP release, we have introduced a new property for configuring the DSC Local Configuration Manager (LCM) called the DebugMode. When set to true, it causes the engine to reload the PowerShell DSC resource. Once you are done writing your resource, you can set it back to false an...
A World of Scripts at your Fingertips – Introducing Script Browser
<Today we have a guest blog entry from Microsoft Customer Services & Support and the Garage> Update: Version 1.1 of the Script Browser is out. Check out the announcement here: http://blogs.technet.com/b/onescript/archive/2014/04/29/here-comes-the-update-of-script-browser-amp-script-analyzer-1-1.aspx To reuse script samples on the Internet, the following steps seem quite familiar to IT Pros: wandering through different script galleries, forums and blogs, switching back and forth between webpages and scripting environment, and countless download, copy and paste operations. But all of these will d...
Collecting the Output of Remoting Commands
One question we often get around PowerShell Remoting is "How do I collect the output of remoting commands into a different file for each computer?" For example, you want to invoke a remote command across 1,000 machines as a multi-threaded job and then create 1,000 text files for their output. This is in fact impressively easy in PowerShell due to the automatic properties that we add to remote output. The trick is to just know that it exists :) As you can see in the example, we tag remote output with the computer name from which it originated. If we leverage that property, we can now create o...
What’s in a name? Using prefixes in PowerShell.
We’ve talked about this in the past but it’s time for a reminder. PowerShell uses prefixes in front of nouns to avoid name collisions. Imagine how many collisions there would be if people used the noun “USER” directly. Instead, we have cmdlets *-ADUser, *-VPNUser, and *-RDUser. The use of the prefix avoids name collisions. When there is a name collision, the customer must specify the full name of the cmdlet. Did you know that the full name of Get-ADUser was actually ActiveDirectory\Get-ADUser? How would you feel if you had to type that every time you wanted to invoke that command? The use of prefixes ...
Windows Management Framework V5 Preview
The Windows Management Framework V5 Preview is out! Check out Jeffrey Snover's announcement here.

Want to Automatically Configure Your Machines Using DSC at Initial Boot-up?
Often times, IT Pros want to automate software installation and configuration upon a machine’s initial boot-up. This blog will walk you through how to use Windows PowerShell Desired State Configuration (DSC) to do this. We will show you how to prepare and inject DSC configurations into your bootable media (such as VHDs), so that they are executed during the initial boot-up process. We will discuss three approaches to this process, and give a VHD example for each one. Prerequisites: Option 1 – Inject a DSC configuration (.ps1) into a VHD Our first approach will be to inject a .ps1 with a DSC config...
Reusing Existing Configuration Scripts in PowerShell Desired State Configuration
You are an expert in PowerShell DSC (or maybe not an expert, just someone playing around with configurations in DSC) and have already written fairly large and complex configurations for configuring your environment/data center. Everything is working well and you are a great fan of DSC. There’s only one problem: your work is complicated. Before long, you have a configuration that is hundreds or thousands of lines long – people from many different teams are editing it. Finding and fixing problems becomes nearly impossible… your configuration is just too unwieldy. Then comes a day when there arises a need to add...
Configuring a SQL High Availability Group with DSC
Let's use DSC to configure something complicated! In past blogs, we’ve shown you how to use Windows PowerShell Desired State Configuration (DSC) to configure relatively simple systems. However, the technologies you deal with on a day to day basis can sometimes become complicated. Don’t worry, DSC can still help simplify configuration. Let’s use SQL AlwaysOn Availability Group (AG) as a example. SQL AG is a new SQL feature that enables replication on top of Windows Server Failover Clustering. While the feature is cool, configuring the environment is quite complex. It involves many steps across multiple machi...
DSC Diagnostics Module– Analyze DSC Logs instantly now!
Have you ever witnessed a DSC Configuration run where you had no idea about what it might have done behind the scenes? Well, then your worries end here! During any DSC Operation, the DSC engine writes into windows event logs, which are like bread crumbs that the engine leaves along the way during any execution. If you read the blog here about DSC troubleshooting, you could learn how to use the Get-WinEvent cmdlet to debug a DSC failure using event logs. However, something that really simplifies life is the new module that has been published in Wave 2 of the DSC Resource Kit , called xDscDiagnostics. Introducti...
Need more DSC Resources? Announcing DSC Resource Kit Wave 2

When we shipped DSC in Windows Server 2012 R2, we shipped a platform with great infrastructure for configuration. The next step for any platform like DSC is the creation of resources to make it immediately usable in significant real world scenarios. With the resources we ship...
How to enable Updatable Help for your PowerShell Module
PowerShell 3.0 lets the user update Help content on a per module basis. In this article, I will explain how you can enable this for your own PowerShell module. Prerequisites: Have a new (script/binary) module, help content for the cmdlets of the module, and a server where the help content is located. For this particular exercise I will be using a script module. Here is how my module is organized: C:\Users\frangom\Documents\WindowsPowerShell\modules\TestModule\TestModule.psm1 C:\Users\frangom\Documents\WindowsPowerShell\modules\TestModule\TestModule.psd1 TestModule.psm1 is my script module. There, I defined...
Want to secure credentials in Windows PowerShell Desired State Configuration?
As you start using Windows PowerShell Desired State Configuration (DSC), you might need to specify credentials for resources. In a previous post we showed you how to define a resource that has a credential property. In this post, I’ll discuss how to properly encrypt credentials when used in a DSC configuration. Prerequisites First, let us discuss the requirements to encrypt a DSC configuration. o It is important that you keep the private key secure. Since the public key is all that is needed to encrypt, I recommend you only export the public key to the machine you are writing your configu...
Separating “What” from “Where” in PowerShell DSC
As you already know we introduced PowerShell Desired State Configuration to the world at our TechEd NA 2013 Session. The session also introduced the notion of structural configuration (what) and environmental configuration (where) (at the 25:50 min mark). Structural configuration defines what is needed and does not change based on the environment. For instance, a configuration can require IIS to be installed – whether we have one node, or many nodes, whether it is a development environment or a production environment. It does not matter - we need IIS installed. Environmental configuration defines the environmen...
Using Event Logs to Diagnose Errors in Desired State Configuration
Windows PowerShell Desired State Configuration (DSC), just like any other Windows software, records errors and events in logs that can be viewed from the Event Viewer. However, the trick lies in effectively parsing these logs, so we know exactly why a particular operation failed. In this blog, we explain where the DSC event logs are, and how their content is structured. We also discuss how we can use DSC events for diagnosing failures, and how we can play with the events to gather maximum information from a single DSC operation. We use the term “DSC operation” to identify a single operation that DSC performs f...
Holiday Gift – Desired State Configuration (DSC) Resource Kit Wave-1
Continuing with the tradition of holiday gifts to the PowerShell community, the PowerShell team has just released DSC Resource Kit Wave-1 - a set of PowerShell modules that contain DSC resources and example configurations. The various modules that are part of DSC Resource Kit Wave 1 can be found here. When DSC was introduced in PowerShell v4, we shipped a set of built-in resources. However one of the important features of DSC is the ability to create custom resources in PowerShell. Our previous blog posts detail how to author resources and how to deploy resources. In order to encourage the community to create ...
Automatically resuming Windows PowerShell Workflow jobs at logon
PowerShell Workflow helps IT Pros automate the long running tasks, or workflows, that can affect multiple managed computers or devices at the same time. Windows PowerShell Workflow is designed to be robust and recoverable. The features that are built into Windows PowerShell allow you to restart the target computers and, if the workflow is not yet complete, to reconnect to the target computers automatically and continue with the workflow commands. You can even restart the computer that is running a workflow, which allows you to run the workflow on the local computer, or include the local computer in the list of ...
Windows PowerShell Script Workflow Debugging
Script workflow debugging support is one of two major script debugging enhancements added in Windows PowerShell 4.0. The other new feature is script debugging in remote sessions, which is described in “Windows PowerShell Remote Debugging”. We introduced script workflow in Windows PowerShell 3.0. These are workflows written in the Windows PowerShell language that are compiled into XAML and then run in Windows Workflow Foundation. There is a subset of Windows PowerShell cmdlets that can be called inside a workflow and are executed as special Windows PowerShell workflow activities when the workflow runs. For a ni...
Windows PowerShell Remote Debugging
Windows PowerShell 4.0 includes two major enhancements to the script debugger. First, script debugging now works in remote sessions. Second, we’ve added debugging support for workflow scripts. This blog article describes the new remote debugging support and a following article will describe the new workflow script debugging. Remote Script Debugging in Windows PowerShell Previously, script debugging in Windows PowerShell was limited to scripts running on the local machine. If you tried to set script breakpoints in a remote session it caused an error. Now, in Windows PowerShell 4.0, you can set breakpoints in rem...
PowerShell Security Best Practices

Understanding Meta Configuration in Windows PowerShell Desired State Configuration
UPDATE 2/6/2018 - The latest information regarding LCM configuration is available in the documentation at the following link: https://docs.microsoft.com/en-us/powershell/dsc/metaconfig .......... LCM and Meta Configuration To understand the concept of Meta Configuration, first we need to know what Local Configuration Manager (LCM) is, and what its responsibilities are. In short, LCM is the engine of Windows PowerShell Desired State Configuration (DSC), and it runs on every target node. Whenever we send the DSC configuration document to a node, it’s LCM’s job to parse it and call appropriate resources which ...
How to Deploy and Discover Windows PowerShell Desired State Configuration Resources
A Windows PowerShell Desired State Configuration (DSC) resource contains a module file (*.psm1), an optional data file (*.psd1),and a *.schema.mof file. Details about what each of those files should look like, and how you can create those files using a DSC Resource Designer Tool, are discussed in an earlier blog post. In this blog post, we will explore the following. Deploying DSC resources to the local computer All DSC resources should be deployed in the following folder hierarchy:- $env: psmodulepath (folder) &...

Resource Designer Tool – A walkthrough writing a DSC resource
At the heart of Windows PowerShell Desired State Configuration are the resources. It is the resources which act behind the scenes for DSC to achieve its “make it so” philosophy. DSC ships with a number of resources in-box and you can take a look here for the complete list. However, once you get started with DSC, you may want to write your own resources (which are PowerShell modules) for your particular use case. This post will walk you through creating a custom DSC resource. You can take a look here to get an understanding of the schema/packaging of DSC resources. Attached with this post is the Resource Designer ...
Hungry for more Windows PowerShell Desired State Configuration Resources?
Now that you understand the value and need of Windows PowerShell Desired State Configuration (DSC), and how to declaratively express the intent of machine configuration via the new configuration keyword, you might be wondering how the configuration happens. Configuration on a machine works because of DSC resources. Windows Server 2012 R2 and Windows Management Framework (WMF) 4.0 come with 12 built-in resources, but that’s not all. Like command extensibility of PowerShell, DSC resources are also extensible–you can create new DSC resources to fill the gap. This blog will walk you through the mechanics ...
Understanding CONFIGURATION keyword in Desired State Configuration
Desired State Configuration is a new management platform in Windows Powershell that enables devOps scenarios on Windows. It enables system administrators and devOps to configure a system declaratively, enforce the configuration and reuse configuration. One core aspect of it is the language extension for Configuration keyword in Powershell. You can express configurations of your machine using configuration keyword as shown below which is taken from the MSDN documentation Configuration MyWebConfig { # A Configuration block can have zero or more Node blocks Node "Server001" { ...
Seeking Input on PowerShell Summit Sessions
One of the best things about PowerShell is its strong community. Events like the annual PowerShell Summit are a great way to get involved and learn more about PowerShell.

Configuration in a DevOps world – Windows PowerShell Desired State Configuration
Some background A new breed of configuration management tools has been created to manage the platforms, applications, and infrastructure of the cloud, and keep the cloud running with high availability. The need for these new tools and infrastructure comes from the increase in scale, rapid rate of change, and complexity of the cloud. But existing tools have limited support for Windows. Windows PowerShell Desired State Configuration (DSC) provides a configuration platform built into Windows that is based on open standards. DSC is flexible enough to function reliably and consistently in each stage of t...
PaaP: Windows PowerShell as a Platform – Part 2
In the previous post for this series, we saw how System.Management.Automation.PowerShell class can be used to run PowerShell commands in a C# application. In all those cases, the runspace that we used was created in a default manner. In this post, we'll look at ways to customize the runspace that we create to execute the commands. Why do we need to customize the runspace? For example, there could be scenarios where you don’t want the user to be able to run a particular command that could change the state of the machine. In that case, you can create a runspace without that command and now, the user does not have a...
Using abstract syntax trees (ASTs) with ISE to make scripting more productive
One thing I really like about Windows PowerShell ISE is its ability to expose its underlying script object model, to allow users to customize the scripting experience to suit their style and need. At the heart of customizing ISE is the $psISE object. The $psISE object allows you to control the various functional aspects of ISE. You can get a good description of the hierarchical object model for $psISE, and an exhaustive list of available features associated with this object here. This post discusses how you can leverage the power of PowerShell's publicly-available parser APIs, and combine that power with the ISE...
WMF 4.0 – Known Issue: Partial Installation without .NET Framework 4.5
With the release of Windows Management Framework 4.0 (WMF 4.0), our package that lets you use management technologies from Windows 8.1 and Windows Server 2012 R2 on some of Microsoft’s older operating systems, we have been hearing one question fairly often. I’d like to address it here, so that there can be more self-help, and hopefully I can help preempt some occurrences of this issue. Scenario: Installing WMF 4.0 on a computer that is not running .NET Framework 4.5 will report that the installation is successful, but the components of WMF 4.0 (such as Windows PowerShell, WMI, etc.) will not be update...
Windows Management Framework 4.0 is now available

Be certain to read this blog post fully before installing, especially because WMF 4.0 is not compatible with certain versions of server products. Windows Management Framework 4.0 Preview was made publicly available in July, and we were very excited to talk with co...
PaaP: Windows PowerShell as a Platform – Part 1
In addition to being a scripting language, Windows PowerShell is also used as a platform in many applications. This is possible because the Windows PowerShell engine can be hosted inside an application. This blog post and the next will deal with the various APIs available for hosting Windows PowerShell in a C# application. The most important type for hosting Windows PowerShell is the System.Management.Automation.PowerShell class. This class provides methods that create a pipeline of commands and then execute those commands in a runspace. AddCommand Let's take a very simple example. Suppose you want to get th...
CIM Cmdlets – Some Tips & Tricks
Common Information Model (CIM) cmdlets have been around for a while, and come in handy when you are performing any CIM operation in PowerShell. They are easy to use, and provide a good user experience. In this blog post, I cover a few tips and tricks that can be useful for users of CIM cmdlets. To get started, let’s get the complete list of cmdlets. The PowerShell module name for these cmdlets is CimCmdlets, and we can use the Get-Command cmdlet to see the cmdlets exposed by this module. Tip#1: Working with CIM sessions A CIM session is a client-side object representing a connection to a loca...

Understanding PowerShell’s Type Conversion Magic
Type Conversion in PowerShell is, without question, one of the most useful ingredients in its "Magic Sauce" of administrator effectiveness. When you run a command with a specific parameter type (I.e.: a DateTime or a TimeSpan), things seem to "just work". For example, consider this recent question / info dump on Twitter: #PowerShell parameters that take a timespan object interpret 10 as 10 ticks, 10:00 as 10 hours, and "10" as 10 days. — June Blender (@juneb_get_help) June 6, 2013 But how? Here are the steps that PowerShell takes on your behalf to convert input to a given ty...
Microsoft Script Explorer: Next Steps
For those who are familiar with Microsoft Script Explorer for Windows PowerShell, you know that we haven't released additional updates to it since we published the release candidate (RC) in August 2012. Over the past few months, we have been talking with customers and partners and taking a hard look at the adoption rate of the RC in terms of the number of downloads and the feedback we're received to date. One of the results of this analysis was that the adoption and usage of the pre-release versions of Script Explorer were not at the level we had hoped. Part of this stems from the fact that customers already have...
Windows PowerShell 3.0 SDK Sample Pack
We're pleased to announce the availability of the Windows PowerShell 3.0 SDK Sample Pack.

Updatable Help speaks only English! What’s up with that?
Our customers have certainly not been shy about their interest in multiple languages of Windows PowerShell Updatable Help, and we're grateful to hear how much they would value localized Help. Our challenge is this: Updatable Help is a new feature for this release of Windows PowerShell, and we have so very many new cmdlets and modules for Windows PowerShell 3.0 (over 2,300 new cmdlets in 95 modules). It takes time to translate the content once it's available in English, and we can't translate all of it. There's just too much new content. One of the Windows PowerShell Core modules just by itself contains over 87,00...

Joining Multiple Tables, Grouping and Evaluating Totals
Joining Multiple Tables, Grouping And Evaluating Totals This is a continuation to the Join-Object blog post considering multiple joins and SQL style grouping and total evaluation. Problem: In the Join-Object blog we’ve seen that relational data naturally organizes in multiple tables. Once we have those tables, we frequently want to see the information back together, so we need something like Join-Object. Sometimes we also need to group the information and evaluate totals inside the groups. For instance, what are the total sales for each customer? How can we use Join-Object in multiple tables and ...

PowerShell 3.0 shipping with Windows server 2012 and Windows 8 brings a new set of Cmdlets to manage any server or device that complies with CIM and WS-Man standards defined by DMTF. In this blog post we will explore these new Cmdlets and how can they help IT Pros in managing a datacenter. The list of new Cmdlets is given in the table below: Basic terminology If you are already familiar with terms like WMI, CIM, WinRM and WS-Man, you can skip this section. CIM: Common Information Model (CIM) is the DMTF standard [DSP0004] for describing the structure and behavior of managed resources such as sto...
New-Workflow –MakeItEasy: Authoring Workflows using PowerShell Extended Syntax
Some time back, in his blog post, Jeffrey Snover introduced one of the new Windows PowerShell 3.0 feature – Windows PowerShell Workflow. In that post, you saw a glimpse of how to author workflows using PowerShell syntax. This post dives into more details of authoring workflows using PowerShell syntax and various extensions to it. Why we chose to extend the PowerShell Language for Workflow Authoring As Jeffrey mentioned in that blog post, Windows Workflow Foundation traditionally has been a developer-focused feature that requires Visual Studio and a lot of code to create a solution. To review the solution, anoth...
Windows PowerShell Web Access – Installation guide II
This blog is a continuation of the post on Basic installation guide for PowerShell Web Access. In the basic installation blog, we configured IIS with the default values used by the Install-PswaWebApplication cmdlet. This is the simplest way to install and configure the feature. The video below illustrates two more ways to configure IIS – 1. Using Install-PswaWebApplication In this case we specify values for –WebSiteName and –WebApplication parameters for the cmdlet 2. Using the GUI equivalent In this case, we use IIS Manager to configure ...
Join-Object
Problem: How do I join two lists of objects into a single list? Or the equivalent: How do I join two CSV files into a single one? Note that joining makes sense only when the two lists or CSV files have something in common. Why do we need Join? If you know why you need join would not enjoy a review of basic database concepts, feel free to skip this section. Say you own a company and want to keep track of the time when your employees arrive. A simplified table of employees could look like this: The id uniquely identifies an employ...
Introducing Management OData Schema Designer
We are excited to introduce the new Management OData Schema Designer tool. The tool’s goal is to accelerate evaluation /development on top of “Management OData IIS Extension” optional Windows Server 2012 feature. A very informative introduction about this feature can be found in the Standards based management in Windows Server 8 by Jeffrey Snover and Wojtek Kozaczynski.

OMI – Open Management Infrastructure to bring the power of PowerShell and standards to devices in your datacenter.
PowerShell community, We are pleased to announce availability of OMI - a highly portable, small footprint, high performance CIM Object Manager. OMI stands for Open Management Infrastructure, and it is available from Open Group as an open source project. See this Windows Server blog post for full details. http://blogs.technet.com/b/windowsserver/archive/2012/06/28/open-management-infrastructure.aspx OMI opens up management of hardware devices in a datacenter using what we call a "Datacenter Abstraction Layer" or DAL. Imagine configuring a set of hardware devices from different vendors (like&...
Snippets in Windows PowerShell ISE 3.0
This blog post applies to the Windows PowerShell Integrated Scripting Environment (ISE) in Windows 8 and Windows Server 2012. The ISE is also fully supported and available when Server 2012 is deployed using the Minimal Server Interface. To start ISE, type ise in a PowerShell console and press Enter Snippets provide a convenient way to paste arbitrary text into the ISE console and script editor, right where you need it. The idea is to provide improved productivity, discoverability, and usability: For those of you who are familiar with Visual Studio’s Snippets, the ISE version uses the same ...
Basic installation guide for Windows PowerShell Web Access
Windows PowerShell Web Access is a new feature in Windows Server 2012. It is an IIS application that provides a Windows PowerShell console in a web browser. The IIS application acts as a gateway between the web browser and the machines that you can connect to in your environment. These machines should have Windows PowerShell remoting enabled. The video below illustrates the three simple steps of setup and configuration – 1. Feature installation In the video we use GUI to install the feature. We could also use the Windows PowerShell cmdlet equivalent for installation (run the cmd in an elevated PowerShell c...
Improving the FileSystem Provider through Community feedback
One of the things we love about the Windows PowerShell community is that folks are not shy. It turns out that having a vocal community is a great way to build and evangelize a product like ours. Of course, the Unix guys had this all figured out a long time ago. Positive comments are good and all, but it’s difficult to really improve without being told where we came short. One of the ways we take feedback from the community for Windows PowerShell is through our public Microsoft Connect site. On that site anyone with a Live ID can log a bug or suggestion against Windows PowerShell. Items then get voted up or ...
Running show-command to discover cmdlets
This blog post applies to the Windows PowerShell Version 3.0. Problem: How can I find out what cmdlets are available for a given task? Finding cmdlets in the traditional way If you know the basics of get-command, feel free to skip this section. If you are searching for a cmdlet to add a printer, you could star with something like: PS C:\Users\mspuser> get-command *printer* CommandType Name ModuleName ----------- ---- ---------- Function Add-Printer PrintManagement Function Add-PrinterDriver PrintManagement ...
High Level Architecture of Windows PowerShell Workflow (Part 2)
This is the second part of our post on the high level architecture of Windows PowerShell Workflow. Part 1 of this blog post provided an overview of the architecture and its various components. This post will go into more detail on the various subcomponents and provide some insight into the internals of Windows PowerShell Workflow. The component diagram for the PowerShell Workflow Executive is repeated (from part 1) for reference Each of the components in the diagram is discussed in detail below. 1. Workflow Compilation, Caching and Validation Windows Workflow Foundation deals with and understan...
High Level Architecture of Windows PowerShell Workflow (Part 1)
1 Summary In March we introduced Windows PowerShell Workflow (PSWF), which explained why we integrated workflows with PowerShell, and what were our major investment areas for our first release. In a recent post, Jeffrey Snover summarizes this decision: “We integrated the Windows Workflow Foundation engine into PowerShell to make it simple and easy to automate things that take a long time, that operate against a very large scale, or that require the coordination of multiple steps across multiple machines.” While these posts talked about workflows as robust multi-machine commands, it didn’t address a...
New V3 Language Features
We’ve already discussed the biggest new PowerShell language feature – workflows – in a previous post. In this post, I’m going to describe a number of small changes we’ve made to the language. Most of the changes described here don’t introduce any new syntax, but I think you’ll agree that most of these changes make various aspects of scripting in PowerShell simpler. To me, many of these features are what make PowerShell a joy to use. Member Enumeration To start, I’m going to describe a little feature that had no official name until I started...
Intellisense in Windows PowerShell ISE 3.0
This blog post applies to the Windows PowerShell Integrated Scripting Environment (ISE) in Windows 8 and Windows Server 2012. The ISE is also fully supported and available when Server 2012 is deployed using the Minimal Server Interface. To start ISE, type ise in a PowerShell console and press Enter Very few things can be considered “cool” in an interactive command-line environment. Intellisense sure counts as one of the few exceptions. While tab completion has always been a cornerstone of PowerShell usability (and continues to be), my struggle with tab completion is that after cycling through the 5th optio...

Improved WMI experience in PowerShell 3.0
There is a famous quote often attributed to Jeffrey Snover, “IT Pros love and hate WMI. They love it because there is so much great stuff there. They hate it because it is complex to use”. Not to our surprise, most of the IT Pros and developers we talked to agree with this. This is going to change with Windows “8”. We listened to your feedback and have made heavy investment in this area. This blog post standards based management in Windows Server 8 by Jeffrey Snover and Wojtek Kozaczynski provides an excellent overview. I would like to highlight two important aspect of improved PS+WMI...

WMF 3.0 Beta is shipped in four...
Scheduling Background Jobs in Windows PowerShell 3.0
One of the most common phone calls that the support team gets for Windows PowerShell is "How do I use Task Scheduler to schedule Windows PowerShell scripts?". As an administrator, you need to have full control over when scripts run in your environment. Perhaps you need run a script only during a one-off maintenance window or maybe you want to schedule some routine maintenance on a server so that it runs at non-peak times. Although it was possible to use Task Scheduler to invoke scripts in Windows PowerShell 2.0, it was not trivial. What's more, you were responsible for writing code to store the detailed results o...
When Windows PowerShell Met Workflow
Meet the new kid on the block! Windows PowerShell Workflow (PSWF) is the latest addition to the Windows PowerShell family. First, let’s establish the context for the decision to integrate workflows into Windows PowerShell. It starts with cloud computing and Windows-based datacenters. Cloud computing provides a set of highly available, scalable computing services that leverage high volume components (servers, disks, RAM, etc.) High volume components are less reliable than their tier 1 counterparts and even those occasionally fail. The key to cloud computing is to use software to deliver a reliable service ...

Introducing Windows PowerShell Web Access in Windows Server 8 Beta
Windows PowerShell Web Access lets you manage your Windows Servers anywhere and anytime. Windows PowerShell MVPs are excited about Windows PowerShell Web Access. We just had a MVP summit here at Microsoft and I had the pleasure of talking to some of our MVPs. Some of them told me that PowerShell Web Access was the best part of Windows Server 8 Beta! Wow, that made me feel good. There are so many awesome things in Windows Server "8" Beta. Windows PowerShell by itself has several valuable improvements. I don’t know about being the best, but Windows PowerShell Web Access is going to be a hit. &nbs...

8 Abstracts for the PowerShell Deep Dive in Frankfurt
We’re super excited about the upcoming PowerShell Deep Dive in Frankfurt on October 17 & 18. The agenda is starting to shape up nicely, so I wanted to share a number of abstracts submitted by members of the PowerShell Community that we’ve already accepted. You can also find this info on The Experts Conference website. Cheap registration of 850 Euros is coming to an end on September 6. If you’re sitting on the fence, hopefully these abstracts will encourage you register while you can still save 150 Euros. And now for the abstracts… Delegated Administration with PowerShell Remoting Speaker: Ale...
Get-Help -Online Fails in German
The Online parameter of the Get-Help cmdlet opens the online version of the help topic for a command in your default Internet browser. If you don't use this feature regularly, you should. Online help topics are typically the most up-to-date version of the help topics, because module authors can update them at any time without redistributing the module. Online help topics are especially critical for modules in the $pshome directory ($env\SystemRoot\System32\WindowsPowerShell\v1.0) which cannot be updated easily, because they are part of Windows. &...
Extending Discounted Registration & Session Proposal Deadline
The deadline for discounted registration of 850 Euros is going to be moved out to Tuesday, September 6.

Deep Dive sessions take on a shorter and more technical format than the standard conference (35 minutes versus the usual 75 minutes). As with the first PowerShell Deep Dive, registration will limit the number o...
Invoke-Expression considered harmful
The PowerShell team frequently gets questions that start out “how do I get the quoting right for…” and the answer turns out to usually be – there is a simpler way – don’t use Invoke-Expression. The problem arises when trying to run some command external to PowerShell. Some common reasons people try Invoke-Expression: If you’re just running some command external to PowerShell (exe, cmd, etc.) and you’re using Invoke-Expression, you are just making things more difficult than you need to. So what’s wrong with Invoke-Expression then? If Invoke-Ex...
Download the Updated Core Help CHM
The best way to get updated help for Windows PowerShell core commands is to type "Get-Help –Online <cmdletname>," but that works only when you're online and your firewall permits Internet access. For all of those other times, there's the new Windows PowerShell 2.0 Core Help – May 2011 Update in CHM format. The newly released CHM includes Windows PowerShell Core cmdlet help, provider help, and conceptual "About" help topics as of May 1, 2011.

Keeping Help Helpful: Use -Online and Redirectable Links
When you refer to Windows PowerShell help topics, such as in tools and blog posts, be sure to refer to the most recent version of the help topics. Few things are less helpful or more confusing than sending a reader to a topic that is missing a parameter or includes an example that doesn't work. To be sure that you're always referring to the newest help topics, refer to the online help topics in the TechNet library. The redirectable links will always be current. Even if a help topic page moves or changes, the redirectable link always connects to the newest version of the hel...

Scaling and Queuing PowerShell Background Jobs
A couple of months ago I had asked the PowerShell MVPs for suggestions on blog topics. Karl Prosser, one of our awesome MVPs, brought up the topic of scaling and queuing background jobs. The scenario is familiar: You have a file containing a bunch of input that you want to process and you don’t want to overburden your computer by starting up hundreds of instances of PowerShell at once to process them. After playing around for about an hour on Friday afternoon, here is what I came up with… This example assumes you have a text file containing the names of many event logs and you want to get the content...

Does Your Hard Work Advance the Ecosystem?
The Lync PowerShell Blog recently posted a fairly chewy piece that described how to enable users in bulk when given an XLS file as input. Jason Helmick responded, saying: Instead of your incredible code that no admin would even begin to understand or even be able to write, let’s do the same thing, in one line. (Note: This is an educated PowerShell admin, or any typical Unix guy.) Step 1: Admin receives xls from HR. They then proceed to use Excel to convert it to CSV. Total time, 10 seconds.

A very touching final goodbye
The PowerShell community lost a great member last night. Carrying out one of his final wishes, his family posted this on Twitter last night: We are sad to tell you, Andy "the most passionate Powersheller" passed away on 12th Jan 2011, and wanted us to say goodbye to you all. Andy https://twitter.com/AndyTearle/status/25414783826141184 Rest in peace, Andy. Update: 11:30 AM – The PowerScripting Podcast has a great post reminiscing about Andy, his family, and his passion: http://powerscripting.wordpress.com/2011/01/13/ripandrew-tearle-the-oldest-powersheller-of-them-all/.
Same Command. Different Return Types.
My command seems to behave differently depending on how many items were returned. This is something that the PowerShell Team hears from the community or our internal partners every couple of weeks. This blog post will explain when a Windows PowerShell command returns different types and offer some reasons for why it is done this way. In general, Windows PowerShell commands can return one of three things: Executing the commands below returned each of the types listed above. (Get-Service foobar).GetType() (Get-Service NetLogon).GetType() (Get-Service Net*).GetType() ...

PowerGUI Scripting Challenge
One of the best ways to learn a technology or take your understanding to the next level is to challenge yourself by entering a contest. Well, here is your opportunity. The Quest Software PowerGUI Challenge contest is currently ongoing and finishes on November 15th, 2010. This contest gives you an opportunity to win a gift certificate for Amazon.com (you can win a certificate worth up to $1000) while having fun with PowerShell and learning more about PowerGUI, a PowerShell script editor and management console. PowerShell Version 2 provided SO MANY new functions and capabili...
Domain Specific Languages (DSLs) – In General and How PowerShell Relates
While attending JAOO, I had the great pleasure to meet and talk with Martin Fowler and Neil Ford on the topic of Domain Specific Languages (DSLs). Channel 9 videotaped that discussion and you can watch it HERE. I'm quite passionate about DSLs - both FOR them and AGAINST them. The details matter! I have this concept called, "Beer Cardinality" and it applies to DSLs. Here is the way it works: Have no beers => Yawn!Have 1 beers => What's the point?Have 2-6 beers => Happy Happy!Have 24 beers => Vomiting, hangovers, regret regret regret DSL...
“A jug fills drop by drop” – Quest PKI Cmdlets
The Buddha once said that, “A jug fills drop by drop”. In this case, the jug is universal PowerShell cmdlet coverage which is a really large jug! We’ve never been confused on this point – I’ve often referred to it as the “30 year hole” that we needed to dig ourselves out of. When PowerShell V1 shipped, it had a very small number of cmdlets. It was mostly used by advanced scripters to script their own solutions. Soon afterwards, the Exchange team released 400+ cmdlets and then it was reasonable for Exchange admins to manage their Exchange task...
Designing Cmdlets That Have Lots of Parameters
We often get the question of what to do about a cmdlet that has lots of parameters. Do you break it up into multiple commands or just have a single cmdlet with lots of parameters. Here is the way I think about it: If you have to enter 100 things to get a job done, it doesn’t really matter whether you enter those 100 things via 1 cmdlet with 100 parameters or 10 cmdlets with 10 parameters each. If anything, there are a number of good reasons to have 1 cmdlet with 100 parameters including the fact that you don’t have to enter 10 cmdlets and you produce an abstraction which is much more friendly t...
Intel vPro PowerShell Module
Intel has released version 1.0 of their Intel Core vPro PowerShell Module. This set of cmdlets do Out-of-Band hardware management of devices that are equipped with the vPro chip. What that means is that you can do a certain amount of management on devices that don’t have an OS or whose OS is hung (if you are using one of our competitor’s OSes .. or haven’t upgraded to the awesome W7 ). This allows you do things like turn machines on or off, change the boot sequence, change power plans etc. Now in all honesty, this module provides you nothing new. You could always use the WINRM executable to perform thes...
PowerShell V2.0 Book Available in Italian
Efran Cobisi has published a PowerShell V2 book in Italian. The title is “Windows PowerShell 2.0 – Guida completa” and is a 448 pages long. Efran describes it as “a collection of theory, insides and hints on the scripting environment, the programming language and the most used cmdlets. It’s targeted to both developers and IT professionals and contains many sections devoted to help people with previous experiences "with other shells (CMD, COMMAND.COM, BASH, KSH, CSH, ...) as well.” If you can read Italian, you can find out more about it HERE. Sadly I don’t read Italian but I’ve visited Rome a number of tim...
Improving Parameter Set Design
Designing useable cmdlets is part engineering and part art. It’s not an easy task to define the conceptual boundaries of a cmdlet (where does one cmdlet end and the next begin) or to provide great feature control without inundating the user with parameters. However, you can improve the usability of your cmdlets by avoiding two common parameter set design flaws. Parameter sets with no mandatory parameters Some cmdlets, like Get-Process, can be run without any parameters, so you'd expect them to have at least one parameter set with no mandatory parameters. But look at the syntax of Get-WmiObject. The firs...
Using New-WebServiceProxy to get, modify, and add items to a list in SharePoint 2007
The motivation Let’s say that you want to retrieve and modify a list in a SharePoint site, but you don’t have access to Microsoft.SharePoint.dll. One possible solution is to try to search online or ask someone to let you copy the dll. If you are able to get a hold of it, you will quickly realize that the Microsoft.SharePoint.dll has some dependencies and that you are stuck again. Well, I will show you how you can get, modify and add items to a list in SharePoint using PowerShell V2. Pre requisites: First, you need a SharePoint site and credentials to modify that particular list. The illustration below shows...
Windows PowerShell 2.0 on Windows Update
Today, we released Windows PowerShell 2.0 and WinRM 2.0 for pre-Windows 7 operating systems on Windows Update. This non-security, optional update is designed for Windows Server 2008 SP2, Windows Vista SP2, Windows Server 2003 SP2, and Windows XP SP3. Windows PowerShell 2.0 and WinRM 2.0 are also available as part of the Windows Management Framework (WMF) Core Package on the Microsoft Download Center and Windows Server Update Services (WSUS). The WMF Core Package available on the Microsoft Download Center and the Windows Update release contain the same binaries of the product...
Specifying a View in TechNet and MSDN URIs
[This isn't only a PowerShell topic, but I've been asked a few times, so I thought I post the answer here.] If you've visited TechNet or MSDN lately, you'll notice that there are new view options for the pages. TechNet has a new ScriptFree view, in addition to the familiar Classic view. MSDN has two new views, ScriptFree and Lightweight. When you change your page view, your preference is saved and new pages that you open are shown in the saved view until you change your view again. If you are linking to a page, you can specify a view in the link. This allows you to determine how users see the linked page. For exa...

Kudos to NetApp for Data ONTAP PowerShell ToolKit
Kudos to NetApp for releasing the Data ONTAP PowerShell Toolkit last week at TechEd. I was monitoring the twitter feeds last week and saw a flurry of activity talking about NetApp’s broad adoption of PowerShell and release of the Data ONTAP PowerShell Toolkit surfacing all of their management functionality through cmdlets. I decided to investigate and headed to the NetApp booth where I saw an awesome, live automated, disaster recovery demo driven entirely by PowerShell. We’re talking automated failover to a remote site in less than three minutes using a combination of the NetApp cmdlets, cluster cmdlets and wha...
Export and Import PowerShell ISE Opened Files
Unlike other tools, PowerShell ISE doesn’t have project files. Project files are a good way to set your environment up with a well known state. Thanks to the ISE Object Model, it is possible to add some project functionality. The script below has two main functions “Export-ISEState” and “Import-ISEState”. They can be used to save files and PowerShellTabs and reopen them later. Even script contents for untitled files are saved. To save the current state (state = files and PowerShellTabs), use something like: Export-ISEState c:\temp\files.isexml To load the state la...
Save All PowerShell ISE files
PowerShell ISE is a simple tool and in some cases it has the bare essentials. For instance, it does not have an option to save all files. On the flipside, it offers an Object Model from its first version that allows adding features beyond the essentials like this one and many more. If we had the "Save All" option in the ISE, one interesting question is what to do about untitled files. They are supposed to be transient. One could argue that Save All could just skip untitled files. Another could argue that we should just pick a name for untitled, but I would disagree with "another" :-) Picking a na...
Renaming Tabs in the ISE
When you have multiple PowerShell tabs open in the ISE, it may be handy to rename them, so you can tell which is which. This is especially useful when using Remoting with Enter-PSSession. The problem when using Enter-PSSession is that you have no access to the root ISE object ($psise) when remoting, so you should use another (local) tab and enter the following: $psise.PowerShellTabs[0].DisplayName = 'myRemoteMachine' Needless to say, if you want to rename the second tab, you'd use PowerShellTabs[1] ... and so on To rename the current PowerShell tab, enter: $psise.Curren...
PowerShell V2 IS Available
Superstar Tobias Weltner (of PowerShell.com and Powershell Plus fame) sent me some mail today pointing to this May 14th article Three Essential PowerShell 2.0 Remote Management Features. It is a very good article except for this part: “PowerShell 2.0 is built into Windows Server 2008 R2 and Windows 7. For older operating systems, PowerShell 2.0 is scheduled to be available a few months down the road and will include support for Windows XP SP3, Windows Server 2003 SP2, Windows Vista SP1 and Windows Server 2008.” That is not right. PowerShell V2 has been available for these OS for quite some t...

Smiling, Crying, and Scripting
I once heard that everyone in the world smiles and cries the same way - that language and culture had no effect on these. I thought of that when I navigated to: http://www.computerworld.jp/topics/mws/180709.html I have ABSOLUTELY no clue what they are saying but in the middle of the article I saw this: I guess everyone in the world scripts the same way too.

Select-String -Context
A lot of people use Select-String but I haven’t seen much discussion of the –Context parameter. This is an awesome feature that we added in V2.

Configuring WSMAN Limits
As you probably know by now, all of PowerShell remoting is done via streaming extensions to WSMAN. WSMAN is the SOAP-based DMTF standard protocol for managing everything. As you explore the limits of what you can do with WSMAN or PowerShell remoting, you may encounter errors like this: [7592:0]PS> New-PSSession [localhost] Connecting to remote server failed with the following error me ssage : The WS-Management service cannot process the request. This user is allowed a maximum number of 5 concurrent shells, which has been exceeded. Close existing shells or raise the quota for this user. For more inf...
A PowerShell Wander: ToolBox Mindset, –ExpandProperty, DMZs and Remote Profiles
I was reading PowerShell remoting in Windows Server 2008 R2. The great thing about this article is that it documents how to use Group Policy to enable PSRemoting on lots of machines automatically. In the article there was the following heads up: Warning: Commands that are executed against a remote machine do not have access to information defined within your local profile. As such, commands that use a function or alias defined in your local profile will fail unless they are defined on the remote machine as well. The great thing about PowerShell is that it is a toolbox.

MMS Partner Presentation: Windows Management Framework
MMS Partner Day focuses on ISVs that produce products for Windows and System Center. I talked to them about the Windows Management Framework (WMF) and encouraged them all to check it out and begin using it to build their products.

“Falling is Learning – Just Focus on Having Fun”
Back in the days when our hair was on fire with security issues, we brought in a number of industry experts to educate us on developing secure software. This resulted in the Security Development Lifecycle which all our products now use. One of the best talks was a from a guy from the NSA who had a talk that was something along the lines of, “The zen of secure software”. In this talk he argued against the all-or-nothing mindset in favor of a model of constantly expanding the envelope. Any given moment, you evaluate what you need to do (in this case – to address security issues), you d...
Fun – Is W7 Too Good?
Sean Kearney (aka Ye110beard of Highway to PowersHell fame ) sent me a pointer to a fun video which posits that maybe W7 is TOO good. Just maybe it is so good that it will put IT Pros out of business. I think the exact opposite is true - I think PowerShell and the ability script the OS and products allows IT Pros to generate a ton of value and increase their integrated lifetime earnings. Still it is a fun video. You can catch it HERE. Enjoy! Jeffrey Snover [MSFT] Distinguished Engineer Visit the Windows PowerShell Team blog at: http://blogs.msdn.com/PowerShell ...

Windows Management Framework Install Failure and Investigation
Since Windows Management Framework was released Oct. 2009, our customers have been excited about using PowerShell 2.0 on down-level OSes. Meanwhile, we also received feedback from both internal and external customers about our product issues. One of them is WMF install failure followed by the mysterious “The update does not apply to your system” error message. It is a blocking issue for some customers since they cannot get WMF successfully installed and the error message does not help much with a fix. 1. Reinstall. In some cases WMF(KB968930) had already been deployed on the machine by the system administrato...
Building on PowerShell: Execution Policies
One question we sometimes get asked is why Exchange changes PowerShell’s execution policy from “Restricted” to “RemoteSigned.” Doesn’t that lower PowerShell’s security? The "Restricted" execution policy isn't intended to be something that PowerShell users live with forever. It's a safe default that protects non PowerShell users from being impacted by PowerShell-based malware. For example, many home users had never used VBScript, but still got bitten by the flurry of WSH-based viruses that got mailed to them. PowerShell's Restricted execution policy solves this. To an attacker, a computer that has never used Power...
Workaround to Catch Exceptions from Import-CliXml
Recently, I came across an interesting bug in PowerShell. Let’s create a repro. First, we create a string “a” and generate an xml based representation of it using the Export-Clixml cmdlet. Since we need to have the class id, we pipe the string to format-table as shown in the example below. Here is the content of the xml file. Then, we remove the class id (in blue) and save the xml file. Next, we recreate an object using the import-cliXml cmdlet and we assign it to a variable, i.e. $a. We should get an exception because the class id is missing but, we do not. On the other hand, if we execute the same co...
Viewing Junctions with ‘dir’
One feature of the NTFS file system is the junction, which is similar to a short cut but works at the file system level. This lets you link one directory to another. There’s a tool called ‘junction’ available here that lets you manipulate junctions. When listing the contents of a directory, by default PowerShell doesn’t tell you which sub-directories are junctions. I wanted to be able to tell which ones were junctions when doing a ‘dir’. The way I did that was to copy the built in file system formatting file, modify it so that junctions are indicated, then load it with Update-FormatData: The file system format...

How objects are sent to and from remote sessions
Instead of piping unstructured text, Windows PowerShell pipes objects between commands in a pipeline. As a consequence PowerShell remoting also deals with objects when passing data to and from remote sessions. This post explains how remote objects are serialized and which types of objects can be sent with full fidelity. You might want to refer to this post when passing arguments to remote commands or when designing remoting-friendly cmdlets or functions. Property bags You might have noticed “Deserialized” prefix in front of type names of some objects received from a remote session: Objects ...

“To ship is the choose.” That is the sad reality behind a number of the things that we regretted about V1. When we first started the project (a LONG time ago) we knew that we wanted to close the semantic gap between what admins thought and what they had to type.

Workaround for Start-Transcript on native processes
Introduction Recently, we came across an interesting bug that had been around for awhile (http://connect.microsoft.com/PowerShell/feedback/ViewFeedback.aspx?FeedbackID=315875). If you do the following: Start-Transcript ipconfig Stop-Transcript If you look at the transcript, you’ll see that the output of ipconfig was not captured. Why is this happening? PowerShell recognizes that ipconfig is a native console application. Since many of these applications do direct writes to the console buffer (i.e. more.com, edit.com etc.), we don’t direct the output handles. Because of that, we can’t capture their outpu...

Saving remote session to your local disk
Read the previous post on implict remoting to learn how the Import-PSSession cmdlet makes it easier to work with remote commands by presenting them as if they were local commands. This user experience saves you the trouble of typing long Invoke-Command incantations to pass arguments to remote commands or to download remote help content. The next great thing would be to jump straight into the implicit remoting experience without having to explicitly set up a remote session each time and having to remember how to invoke Import-PSSession... This is where Export-PSSession cmdlet comes handy - it can be used to save...
Bringing remote commands to your local session
How can you manage multiple technologies installed on separate machines that expose their management surface through cmdlets? One approach would be to open remote desktop connection to each of those machines, another approach would be to send commands using Invoke-Command and PowerShell Remoting. But remote desktop is not a feasible solution for automation and invoking remote commands using Invoke-Command cmdlet can sometimes get burdensome - tab completion is missing, verbose incantations are needed for passing arguments to remote commands and Get-Help -Online doesn't quite work in a remote session. ...
How to pass arguments for remote commands
When invoking remote commands, one often wants to use local values as arguments to the remote command. This post explains how to do that. Hardcoded values Let's start with a simple example. Below you can see how Get-Process is invoked in a remote session when the Id parameter is set to 0: Passing local values What if we want to calculate the value of the Id parameter programmatically, instead of hard-coding it to a particular integer? Well, script blocks can declare parameters and the param block can be used to pass a value to the command that is being invoked. In the following example, we declare the $proce...

We’ve also heard the occasional question on whether it’s possible to install them independently. When we’ve heard this concern, it is usually focused on security. To be clear, Windows Remote Management (WinRM) has been part of Windows since Vista and Server 2008. It does not listen to network connections by default, and must be explicitly activated. Both have advanced greatly during the release of Windows 7 – most notably by working togethe...

I Can Do That With 1 Line of PowerShell: Installed Software
Ying Li has a cool PowerShell Script to list installed Software on a local computer HERE. When I looked at it and thought to myself, I can do that with 1 line (if I cheat a little). Here it is: PS> gp HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |Select DisplayName, DisplayVersion, Publisher, InstallDate, HelpLink, UninstallString |ogv Here is what you get for that 1 line of code: I cheated by using OGV (Out-GridView). Ying used Excel and the output is nicer. But when you only want to spend a single line… :-) Experiment!&...

Windows Server 2008 R2 Rocks!
One of the things I like to say is that, “Microsoft is incapable of sustained error”. By that I mean that Microsoft is an intensely self-conscious culture, fearless about confronting shortcomings and constantly looking for ways to do things better. We beat ourselves up pretty brutally about the shortcomings of Vista and committed ourselves to doing better going forward. This is one of the reasons why Windows Server 2008 was such a good release. We didn’t stop there, we raised the bar for Windows 7 and Windows Server 2008 R2. Part of that was the product itself. Anyone that use...

Why is Get-ChildItem so Slow?
We get this question fairly frequently when it comes to slow network connections. The performance of directory listings (especially on a laggy network) are limited by the .NET APIs we call to retrieve the directory information. There are two limitations to the current set of APIs: Forced Retrieval of Attributes When we do a directory listing, we show the standard attributes of the file or directory: Mode, LastWriteTime, Length, and Name. The core Windows API is highly optimized for this basic scenario, and returns these attributes by default along with the rest of the file information. However, the .NET Framew...
Workaround for Add-Member on plain .Net objects
Introduction While I was fixing bugs, I came across an interesting bug (https://connect.microsoft.com/PowerShell/feedback/ViewFeedback.aspx?FeedbackID=382818) that seemed to have a very simple fix upon first glance. However, after doing some more research, I found out that it was actually very tricky to fix the root cause. If you do the following: $table = @{ key1="val1"; key2="val2" } Add-Member -in $table -MemberType NoteProperty -Name test -Value testValue Now if you pipe $table to Get-Member you will notice that the test property is missing. No matter how many times you repeat t...
Quick, Dirty, Super-Useful Scripting
Last weekend I installed the super-awesome W7 Ultimate on all the machines at home. This weekend I decided to install the XP Virtual mode download. I started to do this and noticed that it was 500MB. That is large and is going to take a long time FOR EACH PC I have. One of the reasons I got the Ultimate SKU is that it has BranchCache. This is EXACTLY what Branchcache was designed to do. One PC downloads something and puts it into a distributed cache and then when the other PCs go to download it, they get it from their peers instead of from the internet (given the way my son rea...
Sending Automated emails with Send-MailMessage, ConvertTo-HTML, and the PowerShellPack’s TaskScheduler module
On October 15th I released a large collection of scripts called the PowerShellPack. The PowerShellPack has tons of PowerShell V2 scripts that can be used to do all sorts of fun and practical things. Today, we’ll show how to use a module in the PowerShell Pack to schedule sending a daily automated email with information about the installed programs on a given system. Turning the output of a PowerShell script into an automated email is a snap in PowerShell V2, thanks to a nifty new cmdlet called Send-MailMessage. Send-MailMessage sends out emails with the credentials of the current user (or an ar...
Windows Management Framework is here!
Windows Management Framework, which includes Windows PowerShell 2.0, WinRM 2.0, and BITS 4.0, was officially released to the world this morning. By providing a consistent management interface across the various flavors of Windows, we are making our platform that much more attractive to deploy. IT Professionals can now easily manage their Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 machines through PowerShell remoting – that’s a huge win! You can download the packages here: http://go.microsoft.com/fwlink/?LinkID=151321 Lee Holmes [MSFT]
Tonight is the Virtual Launch Party @ PowerScripting Podcast
Tonight is the night! I was super happy when we shipped V1 of PowerShell. It started the journey. That said, V2 is the release that we really wanted to release.

Announcing: Open Source PowerShell Cmdlet and Help Designer
http://www.codeplex.com/CmdletDesigner During the development of Windows 7, most cmdlet design and help authoring in Microsoft went through an internal tool called the “Cmdlet Designer.” The Cmdlet Designer makes it much easier for teams to concentrate on the design, naming, and consistency of their cmdlets, while also guaranteeing name registration and collision avoidance across Microsoft. To sweeten the deal, it offers: So why blog about it? Because it’s now yours! We just posted the entirety of the Cmdlet Designer, its source code, design specification, and deployment guide to ht...
Introducing the Windows 7 Resource Kit PowerShell Pack
Since I work on the PowerShell team, I’ve been lucky enough to get a couple of years jump start on producing PowerShell V2 scripts and modules. With every new script I write in V2 I get more and more amazed by the possibilities in PowerShell. I’ve discovered how to do many cool things that, as some of my colleagues outside of the PowerShell team have put it, have showed them the Power of PowerShell. At each CTP of PowerShell, I’ve tried to share this power of PowerShell here on this blog. Thanks to Mitch Tulloch (the main author of the Windows 7 Resource Kit) and Ed Wilson (the Scripting Guy), I...
What's Up With Command Prefixes?
We like to say that PowerShell uses Verb-Noun naming. If we were accurate, we would say that PowerShell uses Verb-PrefixNoun naming. For instance: Get-WinEvent . WIN is a prefix for Windows. Every now and again people look at this and ask “what's up with command prefixes ?!?”. Actually, the question usually comes from teams that are implementing Cmdlets and don't understand why they have to use prefixes. They sometimes feel like their noun is unique or they want to own the noun or they think they may get reorganized into a different group so they are not sure what a good prefix...

Select –ExpandProperty <PropertyName>
Most of us are familiar with the traditional use of Select –ExpandProperty <propertyname>. This takes a the value of an incoming object, enumerates its values and outputs each of those values as a single record on the output stream after adding any properties specified by the –PROPERTIES <propertyname[]> parameter. An example will help: PS> gps |Select -ExpandProperty Modules -ea SilentlyContinue |Group ModuleName |Sort Count |Select -Last 4 Count Name Group ...
The Glory of Quick and Dirty Scripting
One of the things I want us to consider doing in the future is to leverage our Universal Code Execution infrastructure to execute any kind of code. For example, imagine that I have some script foo.vbs, I’d like to do the following: PS> Invoke-Command –FilePath foo.vbs –computer (cat servers.txt) I was about to file a record for us to consider this and thought – wait – I bet that there are other commands that take a FilePath need to be updated as well. The question is – which commands take the FilePath parameter? As I write this up, I now remember the correct solution to this question....
What’s New in PowerShell V2 – By Joel “Jaykul” Bennett
PowerShell MVP Jaykul gave a presentation to the NY PowerShell user group and was kind enough to post the text of his slides HERE. One of the problems I have in talking about V2 is that there is SO much good stuff that I often get the levelling wrong – spending too much time on one area and then needing to skip over others. Jaykul slides are great because they tell the PowerShell V2 story at a consistent level. You should definitely check them out and consider using this as a template if you need to give a PowerShell V2 talk to your friends. Good job! Enjoy! Jeffrey Snover [MSFT] Distingui...
Analyzing Weblog Data Using the Admin Development Model
Someone just tweeted a link to Scott Hanselman’s 2007 blog (an oldie but goodie) about how he used PowerShell to analyze the WebLog data from his podcasts. He provides a beautiful example of I like to call the “Admin Development model”. The whole point of the Admin Development Model is that you use tools to quickly and iteratively investigate things until you have an answer and then you are done or you take take the next step and capture the final solution into a script that you’ll use in the future. Over time, if you use the script more and more often, you’ll add to it and make it more formal a...

Exploring WMI with PowerShell V2
I was messing around with my son’s computer today trying to figure out why one of his programs wouldn’t work. I was going to use ProcMon to monitor the processes but wasn’t sure what the processes where. So first I had to figure out what processes were getting started when I ran his program. I guessed that there was a WMI event for this but as always with WMI – WHAT IS THE NAME OF THE EVENT? In the past, this is where things stopped. WMI was awesome but god help you if you didn’t know exactly what you wanted. We made this a ton easier in PowerShell V2 so I decided to give it a try.&...

Get-SystemUptime and Working with the WMI Date Format
I just got a quick ping from someone at work for an uptime script. I checked in WMI with by using Search-WmiHelp to find a wmi class that had an uptime property (Win32_OperatingSystem has LastBootUpTime). While I had found the uptime property I needed, I was left with another pretty common problem that people hit (in VBScript and in PowerShell) about dealing with WMI times. WMI has a couple of date time formats, and moving in and out of these formats often involves messy parsing code. Luckily, the WMI team was nice enough to make sure that the .NET classes you use to work with WMI can conv...

Dynamic binary modules
Using add-type and import-module you can dynamically compile and load an assembly without any intermediate assembly files to cleanup. For instance, to run a cmdlet on a remote machine you could send over the cmdlet source code, compile, import, and run it all on the fly. Let’s say you have your cmdlet called Use-MyCmdlet as C# code in the file mycode.cs: This example gets the C# code as a string and starts a remote session. It then compiles the code in the remote session with Add-Type and passes the resulting assembly object to import-module. The cmdlet Use-MyCmdlet is invoked in the remote ...

Evolution vs. Intelligent Design
I’m watching a cool talk by Greg Kroah Hartman about the Linux Kernel. He just said something that I absolutely LOVE and feel great kinship towards. He said that the joke in the Linux community is that “Linux is not ‘Intelligent Design’, it’s ‘Evolution’. Which means we react to stimuli that’s happening in the world … we don’t over-plan things”. I think that is a great mindset. This is one of the things we wanted to achieve with PowerShell, to give you the tools that allowed you to respond to the world as it changed instead of us trying to deliver a fixed scenario and then if...

Clean codeThe best route, is to make sure code is clean, and common errors are caught. To do so, runSet-StrictMode -Version 2 Note, there’s a lot of normal PowerShell (v1 and V2) that StrictMode barfs on, so its recommend to only use Set-StrictMode when trying to debug their own scripts. You can also change your error, and warning preference to make PowerShell...
Function Help Cannot Share a Cmdlet Help File
In Windows PowerShell 2.0, you can write help topics for functions, scripts, and modules, just as you do for cmdlets and providers. In fact, as a best practice, you should always include help topics for all shared PowerShell items. And we make it easy. For functions and scripts, you can write comment-based help topics right in the script or function (see about_Comment_Based_Help) or you can write XML-based help topics that use the same schema as cmdlet help topics. .To do so, just add the .ExternalHelp comment keyword to the function or script followed by the path and name of the XML file that contains the...

Assigning the Output of a SWITCH Statement
I was just reading the whitepaper Automating Citrix XenApp on XenServer deployments on HP ProLiant servers. The reason why this works well for them is that the HP Insight Rapid Deployment (RDP) software has the ability to launch scripts at various points. Citrix has a wide range of cmdlets so they are able to put together a pretty nice bundle and offer it in a way that allows you to change it if you don't like it. In fact my favorite part of the paper was this: Create your own cmdlets for a XenServer environment If the cmdlets developed by Citrix do not meet the needs of your environment, you ca...

Detection logic for PowerShell installation
"How do we programmatically detect that PowerShell is installed ?" - This question has started coming up frequently as more folks (both internally and externally) have started to build applications with PowerShell support. As we approach Win7/W2K8-R2 release, which will include PowerShell 2.0 in-box, it is pertinent to have the right guidance out for PowerShell detection logic. If you're writing an installer which relies on PowerShell presence, not only do you need to detect whether PowerShell is installed, but also what version of PowerShell is installed.

Managing Remote Sessions
PowerShell V2 introduces a new capability which allows you to remotely manage machines in your organization. You may have already tried this new feature. In this blog, I will show how an administrator can manage different remote sessions (created by different users from different clients) Scenario: Using PowerShell remoting, normal users can perform non-admin tasks on a machine remotely. There might be situations where an Administrator of the machine may want to terminate specific sessions created by specific users. This Administrator task can be achieved by just restarting WinRM service. However this is n...
Peering into script modules
Sometimes it’s handy to access internal elements of script modules. For instance you may be using a 3rd party module in your application and would like to see the internal state for debugging purposes. This can be accomplished with the invoke operator (&) which allows you to access a modules session state: & $module {script block} The script block is executed in the context of the module. Create a script module that exports nothing: Save to a file ‘NoExport.psm1’, import the module and assign to a variable: If we try to call function ‘Hidden’ we get an error because it was no...
Getting Started with AppLocker management using Powershell
Have you tried out the new AppLocker feature in Windows 7? If not, check it out here and here. Also check out the AppLocker references during TechEd here along with a related video here. AppLocker allows you to specify applications that can or cannot run on the machines in your network. AppLocker’s management tools are optimized towards creating an “allow list” of applications i.e. the list of applications that are allowed to run. Applications not on the allow list are blocked by the system. Perhaps, you have been intrigued by “allow listing” and have tried to implement this approach to get a control over t...
PowerShell 2.0 – Differences Between Win7Beta and Win7RC
Oisin Grehan, PowerShell MVP has done a diff between Powershell 2.0 that shipped with Win7 Beta and Win RC... very useful if you have moved to RC build (or planning to do so) http://www.nivot.org/2009/05/22/PowerShellV20DifferencesBetweenCTP3Win7BetaAndWin7RC.aspx. PowerShell team thanks Oisin for this useful blog post. Osama Sajid, Program Manager
Adding Custom Cmdlet Help for Providers
A new feature of Windows PowerShell 2.0 lets you write custom cmdlet help for Windows PowerShell providers. This blog explains how to do it. (The topic will also be covered in excruciating detail in MSDN, but we don't want you to wait.) What's a Provider? A Windows PowerShell provider is a C# program that exposes a data store to Windows PowerShell through a Windows PowerShell drive (PSDrive). When users view the PSDrive, the data in the data store appears to be organized like a file system drive. The drive has a path and users can navigate through the data store by using file system navigation commands lik...

Processing Event Logs in PowerShell
PowerShell V2 ships with two sets of cmdlets for processing event logs, one is *-EventLog set and other is Get-WinEvent. Reading Events: As you can see there are two cmdlets to GET events from event logs , Get-WinEvent and Get-EventLog. Having two cmdlets to do the same thing seems to be counter-intuitive and I will explain the difference between the two to remove the confusion. As we can see, Get-WinEvent can handle a lot more that Get-EventLog does. If you are on Vista and above, Get-WinEvent is the recommend way to read the event logs, use Get-EventLog on XP and Win2k3. A quick check on the n...
V2 Quick Tips: Finding Extra Outputs From Your Script
One of the nifty features of functions in PowerShell is that they can return as many results from as many places as you’d like. In fact, any method or cmdlet that would give you an output if you try it on the command line will also return values from a function. While this can give you a lot of powerful capabilities (like easily building functions that return a list of items), it can also be a source of pain, especially if you have a decently sized script that, every once in a while, produces an unexpected output mixed with expected output. Since you cannot restrict what types get outputted from...

Copy-Acl
Today my wife told me about a problem on the family PC. There were a bunch of PDF files in a directory that had the wrong permissions so my son couldn’t access them. She modified the ACL on one of them using Explorer and verified that that was the fix. (This is from a test I ran) She then selected them all and tried to do it all at once but when she brought up the Properties, it didn’t have the Security Page anymore: She wanted to know if there was some trick to set the ACLs all at once. I told her that PowerShell could do that. I showed her how to use Get-Acl and Set-Acl and...

Fun With Alerts (“`a”)
I just decided to restart Outlook to see if that made some weirdness I was experiencing go away. As you may or may not know, the Outlook process often is running for quite a bit after the Outlook window goes away. As such, you really don’t want to start another instance of Outlook until the first version is done. In V2, we now have the WAIT-PROCESS command so what I wanted to do was: PS> Wait-Process Outlook; Outlook The problem with that is that Outlook is not in the Path so it doesn’t work. I could go figure out how to do this but I didn’t want to spend the time right now so i...

Soliciting New Verbs
With the recent changes in v2 to increase the visibility of the cmdlet design guidelines, we want to make sure we have a solid set of verbs on the approved verb list before we ship v2.

In addition, we'd love to have feedback from our community on any holes you perceive we have in our current list of approved verbs. To provide some context, here are the things we think about when deciding whether to add a new verb: When suggesting a new verb, it's most helpful if you can include the following infor...

Increasing visibility of cmdlet design guidelines
Summary In PowerShell v1, we published a set of cmdlet design guidelines that included direction on how to properly name cmdlets. Throughout the v2 cycle, we've seen an increase in cmdlet authors deviating from the standards in unexpected ways. Our user community (you all) has become particularly vocal in recent months that we needed to do something in v2 to curb this trend. This led to a series of discussions on our team about an appropriate course of action for v2. The outcome of those discussions includes changes to Import-Module where we will perform name checking on imported commands. We decided not to disa...

Checking for bound parameters
I recently read an email where someone was asking how they could check in their function if a value had been provided to one of the parameters. Consider for example, The usual way I’ve seen people deal this problem is by providing a default value which gets assigned to $x in the case that a value wasn’t provided by the caller and then checking for that value. That works in the majority of cases, but let’s say that you wanted to differentiate between a default $null value and $null being passed by the caller. What would you do? If you’re on v2, a simple solution is ...
Setting Network Location to Private
The Network Location feature was introduced in Windows Vista. It provides an easy way to customize your firewall settings based on whether you trust or don’t trust the computers around you. There are three Network Location types - Private, Public and Domain. If your computer is a member of the domain then you won’t be able to change the Network Location type. If your computer is standalone or part of the workgroup, then you can choose what type of network location do you want - Public or Private. Private means that you are a member of the trusted network and you can lower your network security a little bit. Publi...

Image Manipulation in PowerShell
The other week, I showed a Get-ProgID function that I used to help someone at Microsoft Research find a good object to talk to images. A few comments jumped to one of the possible solutions, which is to use the .NET Drawing assembly (which I have to load first). I wanted to be reasonably sure that the way to get at the image metadata was efficient and didn’t require loading up any assemblies PowerShell hadn’t loaded already. Looking at the output of Get-ProgID, Two COM objects jumped out at me: These two COM objects are part of a whole fun family of scriptable COM objects that work with the M...
Active Directory Administrative Center for Windows Server 2008 R2 implemented using ADPowershell!
Windows Server 2008 R2 doesn’t just add ADPowershell – it also adds Active Directory Administrative Center (or ADAC), a new GUI tool for AD administrators. Read about it on TechNet. What’s more, while you can’t tell just from looking at it, ADAC is implemented entirely over Windows PowerShell 2.0 and ADPowershell! Every read and write to AD goes through ADPowerShell. So, if you were wondering whether Windows PowerShell and ADPowershell are just for scripters -- they aren’t! Windows PowerShell and ADPowerShell provide a powerful and flexible management API for the construction of mana...
Get closure with GetNewClosure
Have you ever created scriptblocks on the fly, say in a foreach loop, and they totally mess up because they all have the same value? This is something sort of advanced, and typically used when you’re proxying an object. The most basic example would be, taken from (http://www.powershellcommunity.org/Forums/tabid/54/aff/1/aft/2506/afv/topic/Default.aspx) function add([int]$x) { return { param([int]$y) return $y + $x } }$m2 = add 2$m5 = add 5&$m2 3 #expected: 5 actual: 3&$m5 6 #expected: 11 actual: 6 The value for $x is $null for both. Why is that? Its because $x is $null in the local scope, the script...

Get-ProgID
The other day, a friend over in Microsoft Research wanted to figure out how to get out the width and height of an image in PowerShell. There are many ways that you can approach this particular problem. I knew three right off of the top of my head, but none of them had a really optimal experience. I knew there had to be a better way. Some object had to be able to give me back image width and height as a nice simple property. I normally use two functions to find my way around unfamiliar problems (before I start using search engines). One I’ve shared out a few times is called ...

In cmd, listing files based on attributes was simple: In PowerShell, it’s not so easy: We have had requests to cover the first case better, for example: https://connect.microsoft.com/feedback/ViewFeedback.aspx?SiteID=99&FeedbackID=252549&wa=wsignin1.0 https://connect.microsoft.com/feedback/ViewFeedback.aspx?SiteID=99&FeedbackID=308796&wa=wsignin1.0 We haven’t added such a parameter to Get-ChildItem yet, but with some new features in V2, you can add them yourself. The techniques I describe below can be used to augment any cmdlet, or any script or function for that matter. If you don’t care much a...
Reserving keywords
A couple months ago we asked our MVPs how they felt about reserving keywords in V2. We received some excellent but mixed feedback, so we’d like to open the discussion up a bit wider. There are keywords we hope to use in a future version of PowerShell, but won’t be implemented in V2. “class”, “using”, and “new” are excellent candidates for additions to PowerShell, but we haven’t decided on the exact list yet. Because V1 did not reserve these keywords, reserving them now would be a breaking change. For example, some people like to add an alias like: If we reserved “new”, scripts using this alias w...
Out-GridView Revisited
It has been more than one year since we updated Out-GridView feature with you. In case you are not familiar with Out-GridView yet, it is a unique PowerShell cmdlet that users can pipe command output to a separate window, and it enables users organize and analyze output data easily. The previous blog entry by Brent gave an overview of Out-GridView cmdlet. So, what’s new for Out-GridView in Windows PowerShell CTP3? A major feature we added was query filtering functionality; data can be queried according to their properties through this feature. Let’s look at an example. Running command: “Get-ChildItem | Out-GridV...
How to Create an Object in PowerShell
Today someone in Xbox Live Operations (the folks that keep xBox Live alive and well) pinged me with a simple question about PowerShell with a complicated answer: “How do I create a class in PowerShell?” There’s two scenarios I find where people want classes. The first (and most common) is familiarity: the person wants to make a class in PowerShell because they think of problems in terms of classes. The second is practical: the person wants to make a collection of properties and methods, because that’s what the pipeline in PowerShell plays nicely with (for instance, you can Gro...

PowerShell Folksonomy – Are You In?
A while ago I did some experimentation with a PowerShell folksonomy. The idea was to tag internet content (blogs, comments, newsgroup replies, etc) with unique tags that search engines would pick up and make it easier to find exactly the information you needed. This effort stemmed from an documentation battle we had over the use of the term cmdlet. This was a word that I made up to describe PowerShell commands but I wanted to invoke the idea that these were tiny things that were composed with other tiny things to solve big problems. One of reasons I was hardcore on this idea of a cmdlet b...
Where Did That Come From?
Have you ever found yourself asking the question, "where did THAT come from?"? In PowerShell we try to give you mechanisms you can use to answer questions like that. We spend extra resources (memory, cpu cycles, etc) to do this because we focus in the performance of the PEOPLE using our software instead of the performance of the code. When something goes pear-shaped, what matters is how quickly a person can figure out what is going on and fix it. We've talked quite bit about this in the context of the rich error information we gather but in this blog I'm going to d...
Converting to Array
When you run a PowerShell pipeline, that pipeline might return 0, 1 or many items. If you are assigning the results of that pipeline to a variable, you will get $null, 1 item or an array of items respectively. Sometimes, you won't care about the different types returned, but at other times, you'll actually prefer to force the results to always be an array. In those cases, you can use @( ... ). As in: $a = @(get-childitem) That will evaluate the statements enclosed within the parentheses and collect the results into an array. If there are no results, then you'll get an arra...
Stopping Every Instance of PowerShell.exe (except the one I'm in)
Our Test Architect just dropped by my office and pitched me a PowerShell question with a nice, quick answer. He wanted to stop every process of a particular name, except for the instance that was running the script. You can do this in one nice pipeline: Get-Process Powershell | Where-Object { $_.ID -ne $pid } | Stop-Process Get-Process takes a positional parameter (name), which is a wildcard that supplies the name of the process. It returns back a bunch of ProcessInfo objects, which have a property, ID (the process ID). $pid is a variable that will tell you the current process ID in Powe...
JAOO Talk
Last year I was delighted to be invited to give a talk at JAOO conference. This is a great language conference. The thing I was delighted to discover is that the while it had Microsoft content (AndersH gave one of the keynotes), the bulk of the people and content was non-Microsoft. This allowed me to give a different kind of a talk. It allowed me to go back to the basics and explain what were were doing and why we were doing it to a group of people that didn't necessarily have any background and were potentially not particularly friendly towards Microsoft. (I've got a funny story abo...
#requires your scripts
Recently, I saw someone that had developed a script on the CTP3 drop and was then having trouble running it on v1 of PowerShell. Eventually it turned out that he was using v2 features in his script. Most of you know that we are trying to keep the next version of PowerShell compatible with v1 and I encourage you to report any problems that you might have in that area. Unfortunately, v2 being compatible with v1, doesn’t mean v1 is compatible with v2. After seeing that, I started thinking about people sharing v2 scripts on the web and the problems they might cause someone that didn’...

Console Application (Non) Support in the ISE
There are some limitations on how the ISE interacts with console applications you need to be aware of, for apps like ftp and netsh.First of all, the ISE Runs console apps that don’t require user input just fine.For example, “ping www.microsoft.com” and “cmd /c dir /s”Piping also works fine in the ISE,For example, PS C:\Users\ibrar> "show mode" | netshnetsh>onlineAutomation in scripts, that don’t require user interventions should be fine.However, if you run “cmd /k” which requires input, the ISE will be stuck, and you’ll have to stop the pipeline, using Ctrl-Break or pressing the stop button.It can get annoy...

Getting Alternate Streams (Verbose, Progress, Debug) with the PowerShell API
Dozens of people could write dozens of books on all of the cool stuff we improved in V2 of PowerShell. One of the nice little things we did was give a more understandable API than Pipeline (which is the class you can use to invoke code from C# in V1). This API is called the PowerShell API, and one of the improvements it makes is the ability to get to alternate data streams. Alternate data streams are a particularly fun thing about PowerShell. While you can have a lot of output streams in DOS, it was anyone's guess exactly what any of them were. PowerShell has several alternate data streams that...

Managing Server Features with PowerShell Cmdlets on Windows 2008 Server R2 Beta
If you have used Windows Server 2008, probably you had experience with managing server features. Server Manager is a traditional way to install/uninstall server features. On Windows 2008 Server R2 Beta, Windows PowerShell provides a new approach to managing server features via Server Manager PowerShell cmdlets. This blog will walk through installing server features with these cmdlets. To use the Server Manager cmdlets, we need to import servermanager module by running the PowerShell command “Import-Module servermanager”.

Cmdlets are high level, task-oriented abstractions. The implementation of cmdlets can talk to anything: Web services, COM objects, WMI objects, .NET objects – anything. Depending upon how developers design their API, they can make it easier or harder to write cmdlets. Now that you can write cmdlets in PowerShell itself, here are some tips for designing your API so that it can be easily scripted against and turned into a set of cmdlets using PowerShell Just because the Object Model lives in .NET land, doesn’t mean we can’t make it easier to use for scripte...

A Bit More On BITS
I was in a meeting yesterday talking about BITS and what an awesome service it was. I described what it did and how it allowed people to avoid a wide range of low-class, pain in the butt problems. The question then became, "why isn't everyone using it?" That's a darn good question. The answer is that we have not educated people about it. I aim to fix that. I wrote an earlier blog on BITS HERE. Alex Ng has just written a nice blog about it HERE. Check it out, try it out, tell a friend (and consider the internet a friend). Experiment! Enjoy! Engage! Jef...
Debugging PowerShell Script Using the ISE Editor
Hi writers and consumers of buggy scripts.This post explains the basics of the Graphical Debugger in the ISE. There’s a lot of good stuff, with some tips and tricks.The debugger support got the cmdlets and user interface. The cmdlets include Enable/Disable/Get/Set/Remove-PsBreakpoint and Get-PsCallStack.The general feel is to place breakpoints across the script, continue (F5) to jump from breakpoint to breakpoint, and step over, step into, and step out to move around. You can also get the call stack, and hover over variables to get their values.BreakpointsLine breakpoints are easy to add, with F9 or c...
Why Should I Test With PowerShell?
Today, on our internal discussion list, someone asked if there were any advantages to testing with PowerShell versus testing with C#. I was able to come up with 10 quick reasons to test with PowerShell: I hope these reasons help convince other software testers to use PowerShell. It can really make testing a lot simpler. Hope this helps, James Brundage [MSFT]
Using PowerShell to Protect Against Conficker (Enabling and Disabling AutoRun.inf)
On the front page of MSN.com today, there’s details about a new worm, Conficker, that spreads using the good old fashioned autorun.inf tricks. It infects USB drives so that, when you plug the drive into another computer, it automatically runs and infects the machine. The article mentioned a post on Nick Brown’s blog that instructs you on various ways to disable autorun.inf files and gives a .REG file for disabling autorun.inf. Here’s the .REG file: Recently, I’ve started to like taking small registry hacks and turning them into functions, so here’s a pair of functions that I wrote to automate t...

How To Make Your Own Module Repository
Andy Schneider (from Get-PowerShell.com) recently asked me how he could make sure that everyone at Avanade could get a consistent set of modules. I run into a somewhat similar problem here at Microsoft, where I want to take scripts I've built to work with internal applications and make them easy for people to use, even if they're not already using PowerShell. I don't want the scripts to be broadly available (after all, what is someone outside of Microsoft going to do with a script that works with Product Studio?) but I want the scripts (and PowerShell) to be installed or updated with a single click.

Podcast Discussing WSMAN 1/14/2008
Tomorrow evening I'll be doing the Mind Of Root podcast with Steve Murawski to discuss WSMAN. WSMAN is the new standard management protocol to talk to all sorts of heterogeneous devices and is the protocol that PowerShell Remoting is based upon.

Interactive remoting in CTP3
Today let's talk about one of the cool new features of Windows PowerShell V2 - Interactive Remoting. Let’s start with an example: As you can see Enter-PSSession starts interactive remoting session and Exit-PSSession takes you out of it. The aliases for these commands are etsn and exsn. You can also use exit keyword instead of Exit-PSSession. Interactive remoting uses the same remoting infrastructure as other PowerShell remoting cmdlets. WinRM provides the transport and maintains a listener service, which is responsible for creation of the remote PowerShell sessions. Similar to Invoke-Command, you can use compu...
How to copy colorized script from PowerShell ISE
UPDATED Feb-03-2009: Lee Holmes has posted an updated version of the script which does a much better job of HTML copy-pasting. It can also produce line numbers and has a number of other improvements. In the previous article we demonstrated how to use Console-Copy script to make a colorized copy of console screen and place it in the system clipboard. Now what about doing the same thing with these nice looking colorized scripts that you can see in PowerShell ISE? Direct copy with Ctrl-C will copy just text without colorization. But the cool thing about PowerShell ISE is its great extensibility, which mean...
Please Give Us Feedback
With the release of Win7/WS08R2 beta, we are officially in the end game of PowerShell V2. This is the phase were we can only respond to customer feedback and we rely upon customer feedback to tell us whether and when we are ready to ship. In other words - now is when we need to hear from you the most. I'm very excited about what we are delivering in PowerShell V2. As a community, we are going to be using these bits for many many years so let's work together to ensure that they are the best possible. Experiment! Enjoy! Engage! Jeffrey Snove...

Copy console screen to system clipboard
In the previous example we learned how to create a colorized copy of console in HTML and RTF format. However, the output of these scripts cannot be readily used for pasting into web or word processing applications. To insert it into your article in MS Word format, you need several steps: generate RTF string, save it to an RTF file, then open the file in MS Word, copy its contents and, finally, paste it into your document. Can we reduce it to two steps: run the script, which copies console screen to system clipboard, and then paste the results to MS Word? As a matter of fact we can, but to do this we need to learn...
Colorized capture of console screen in HTML and RTF.
In the previous post we demonstrated how we can use console host API to capture screen buffer contents as text. But what if we want some colors. Would not it be nice to publish colorized copy of console in HTML or insert it as part of Microsoft Word document. For this to work we need to add some modifications to original script. Colors of each character are available as properties of System.Management.Automation.Host.BufferCell object: All we need to do is to iterate through the screen buffer array, keeping track of the cell colors and generate HTML spans or RTF blocks with varying color attributes as soon as t...
Finding a URL For File Transfer Cmdlets
I just posted a blog about our new File Transfer Cmdlets in which I artfully dodged a difficult question: How do you get the URL to do the file transfer? Sometimes you are going to have it but other times you’ll go to a website and it can be bloody impossible to find the URL that you need to download. That was the case with the example I used. Let me provide it. Navigate HERE and tell me if you can find the URLs to download the kits? (If you find out how – let me know – I’d REALLY appreciate it.) My new motto is Experiment, Enjoy, Engage (which means share). Luckily, we have a...
Transferring (Large) Files Using BITs
Have you had a file copy fail? Does that drive you crazy or what? How about when it is a REALLY big file and it takes a couple of hours and JUUUUUST before it finishes something happens to interrupt the transfer and you have to start all over again. Does that make you want to shove a sharpened #2 pencil up your nose or what? I got to thinking about these things when I saw that the W7 and WS08/R2 beta bits were available and that the demand was so high that the servers were having a hard time keeping up. Can you image how you would react if you downloaded a GB and then the transfer failed?&...

Everyone needs to get good with Advanced Functions – this is the easiest path to the best semantics for everyone. In previous posts we’ve shown how you can add a few simple attributes and get a TON of stuff for free. There is a LOT more to advanced functions. You can go VERY VERY far with advanced functions. I can’t think of anything you can do in C# Cmdlet that you can’t do with a PowerShell cmdlet. Many of these functions are made available to you via the $PsCmdlet variable. For example, if you write a Cmdlet which takes multiple ParameterSets, you need to know which Paramete...
Capture console screen
Seeing nicely formatted console examples in a previous post has inspired me to write a script that captures the console screen buffer directly from the Windows PowerShell console host. With this script you can make console "screen shots" to demonstrate some of your favorite Windows PowerShell concepts, and then post them to your blog, or put them on your Web site. How is it done? The console host has a powerful API that is somewhat neglected by most script writers. This API allows you to capture console screen rectangles or output a colorized text in arbitrary areas of the screen. The console...

Get-USB – Using WMI Association Classes in PowerShell
Last Thursday, we had our first meeting of PowerShell Script Club on the Microsoft Campus. Script Clubs are really cool. They're kind of like a hands on lab with no set topic or teacher. You bring an idea for a script, and ask your fellow PowerShell users about help getting the script written. Leave a comment if you’d like to set up a local script club. One of the questions I helped answer involved using a WMI association class, which is a class in WMI that links two other classes together. Association classes are pretty common, and pretty useful, once you get the hang of them. One association class is Wi...

A number of PowerShell MVPs and PowerShell team members are helping me to compile a table of contents for our blog, which basically means that I’m getting to go back and revisit all of the fun stuff posted to the PowerShell blog over the past few years. It’s a fun an educational process, and, hopefully, when we’re done the blog will be a much simpler place to explore.

Extending and/or Modifing Commands with Proxies
There are so many powerful features in V2, it is hard to know where to begin. This one is going to blow to top of your head off when you understand what it enables you to do. In this blog, I talk about Proxy Cmdlets which is the ability for one Cmdlet to call another. You could always do this but to do it right has always been very difficult.

How To Write a Console Application in PowerShell with Add-Type
Windows PowerShell CTP3 has a lot of very cool things. CTP2 introduced the Add-Type cmdlet, which allowed you to dynamically compile C# in PowerShell. It was actually possible to use the CompilerParameters to Add-Type to make a console application, but it wasn't particularly easy. In CTP3, we've made this a lot easier to do. There's now an -OutputType parameter for Add-Type. It can either output a Library (the default), a ConsoleApplication, or a WindowsApplication.

How and Why to Use Splatting (passing [switch] parameters)
On our internal discussion list, someone just asked about how to pass switch parameters from one function to another. This person asked this as "Why can't [switch] parameters be passed as parameters?". My short answer was simple: "They Can Be" Answering this question is a great way to illustrate the value of a PowerShell V2 feature called Splatting. Splatting is two things, it's a way to get all of the parameters passed to a function automatically (they're in a variable, $psBoundParameters), and it's a way to take a list or dictionary of arguments and pass them on to the next fun...

[1/3/09 Update - the original link to the attachment containing this code was broken but is now fixed. Sorry. jps] It is hard to overstate how important Modules and Advanced Functions are.

PowerShell v2 Pipelining in 73 (make that 53) Characters
I started using Twitter and saw a request from Thomas Lee for help about pipelining in CTP3. The thing about Twitter is that the messages have to be tiny so I wasn’t sure I could answer using it. It turns out I can solve this problem AND give a usage example in 73 characters. Here goes: PS> function t{param([Parameter(ValueFromPipeline=1)]$t);process{$t}};1..10|t 1 2 3 4 5 6 7 8 9 10 Now if you put it into a file (which is actually what Thomas asked for), then it is only 53 characters: PS> cat t.ps1 param([Parameter(ValueFromPipeline=1)]$t);process{$t} PS> cat t.ps1 |Measure -Charact...
Resolve-ShortcutFile
If you're like me, you've got a browser favorites folder that is full of wonderful PowerShell code snippets. Ideally, it would be great to have a way to bring those favorite snippets into PowerShell so that my favorites folder becomes a code library. Doing this presents several challenges. The first (and easiest to solve) is getting the web page the shortcut points to out of the .url file. .url files are in the same sort of format as .ini files (each line has a property name, and =, and the value). So to get the url out of a shortcut file, I simply had to Get-Content on the file, pipe it to Where-Object, look f...

Advanced Functions and Test-LeapYear.ps1
Welcome to CTP3! There are just an amazing amount of really important features in V2 but the one I want everyone to start using ASAP is Advanced Functions. In CTP2 we called this cmdlets. We dropped that term in favor of taking the idea of a FUNCTION and just making it more and more capable. It is a bit of a misnomer in that you can have an "Advanced function" by just adding a single line to your script. You'll be amazed what that single line gives you; but we'll explore that later. This entry recaps where we are with functions and then begins to give you a feel for some of the...

Here is an example of how you would code parametersets using advanced functions: function test-param { param( [Parameter(ParameterSetName="p1",Position=0)] [DateTime] $d, [Parameter(ParameterSetName="p2", Position=0)] [int] $i ) switch ($PsCmdlet.ParameterSetName) &n...

Here is a script that I call Mount-SpecialFolders.ps1 which mounts all your special folders as PowerShell drives. # Mount-SpecialFolders.ps1 # param($Folder="*", [SWITCH]$Verbose, [SWITCH]$PassThru) foreach ($f in [Enum]::GetValues([System.Environment+SpecialFolder]) |where {$_ -like $Folder}) { $drive = New-PSDrive -Name $f -PSProvider FileSystem -Root ([Environment]::GetFolderPath($f)) -Scope Global -ErrorAction Silen...

Explore Your [Environment]
This topic is a little long but I strongly encourage you to walk through it and master the techniques it illustrates. I can assure you that you'll will use them a couple thousand times in the next couple of years. .Net provides a wonderful class called System.Environment that tells you all about your environment. It is well worth taking a few minutes to stop what you are doing and explore this class so that you understand its capabilities. That way when a relevant issue comes up, you'll know that there is very simple way to get the answer. First thing to remember is that they way you sp...
Gesticulating Ben Pearce
I gave a talk with Ben Pearce during IT Forum in Barcelona this year. It was the first time I had ever given a talk with Ben as was shocked (and delighted) by his speaking style. Ben is an awesome presenter. Full Stop. That said, one of his presentation techniques is to use of very energetic, very large, very expressive arm movements. No until you understand this, you might think that Ben was having an seizure on stage. (If you watch the first talk you see Ben starting the talk with some wild movements and when it my part of the intro - I just sorta stared at him not knowing ...

Apologizes for the Confusion
If you visited our blog yesterday and were driven to go get a basket of "Freedom Fries" - you can relax.If you visited our blog yesterday and thought we were trying to get some class - I'm sorry to say that that is not the case. The good news is that there is a new PowerShell blog in French at http://blogs.technet.com/powershell/default.aspx . The bad news is that for some reason, this caused our blog (MSDN vs TECHNET) to get redirected to that blog. Obviously it's fixed now. Apologizes for the confusion.

Get-Everyone
Jeffery Snover just posted a Get-Me script. The Get-Me script finds out the principal of the user running PowerShell. In case you ever wanted to know how to get all of the users on a machine (or from a domain), here's a quick function that queries WMI for users. function Get-Everyone([switch]$fromDomain) { #.Synopsis # Gets all users #.Description # Queries WMI to get all users. To save time, queries # are local unless the -fromDomain switch is used #.Parameter fromDomain # If set, gets domain users as well as local accounts #.Example # # Get Al...
PoshBoard and ConvertTo-HashTable
I’m currently watching an cool video of PoshBoard a PowerShell based Web Portal by Pilosite available on CodePlex. It looks great. In the middle of the video I noticed the following script he uses to populate one of the controls on the dashboard: $ht = @{ } $objDrives = gwmi –class “Win32_logicalDisk” –Namespace “root\cimv2” |where {$_.DriveType -eq 3 } foreach ($ObjDisk in $objDrives) { $size = $objDisk.size / 1024 $freespace = $objDisk.FreeSpace / 1024 $IntUsed = ($size - $freeSpace) * 1024 $ht.Add($objDisk.DeviceId...
Verbs vs Nouns by Snapin
A while ago the System Center Virtual Machine Manager team showed me a chart of their cmdlets. It was an Excel spreadsheet which had the VERBs as rows and the NOUNs as columns. I thought that this was a wonderful way to look at the cmdlets. I woke up this morning and decided to write a script which would do something similar. I’ve attached that script which accomplishes that task. In the process, I decided that there is a good general purpose function here but I haven’t figured out what it’s name is so right now I’m just calling it ConvertTo-XXX (I’m open to suggestions).

Step up your FOREACH Game
Last night Bruce Payette and I were interviewed on the PowerScripting Podcast with Hal Rottenberg and Jonathan Walz. It was a blast!

PowerShell_ISE and Visual Studio
Scott Fulton has a good article describing my PDC talk HERE. In it he says, "Starting with version 2, a user can conceivably write new PowerShell cmdlets in PowerShell, using the built-in IDE, completely independently of Visual Studio." This is true but there is more to the story so here it is. PowerShell's Integrated Scripting Environment (ISE) actually uses an editor control which uses the same technology that will be in the next version of Visual Studio. It is a great control and get's better and better with each snapshot we take. We need to stop taking snapshots long before VS because...
VI PowerScripter From icomasoft
icomasoft has just released VI PowerScripter. PowerScripter is a PowerShell based extension module to VMWare's VI Client. I have not seen it but looking at the online manual has got to make any admin start drooling. The thing I like about this so much is that it leverages both PowerGadgets and PowerGUI. This allows them to deliver a great experience to their customers without having to code it all themselves. As those products get better, their product gets better. Happy happy all around. I haven't used it (since I don't have a big VMWare environment [surprise :-) ]) so I...
574 Reasons Why We Are So Proud and Optimistic About W7 and WS08R2
In my previous blog post, I mentioned that we were all very proud and optimistic about W7 and WS08R2. There are tons of reasons for this including how well the project has been run, the hardcore focus on quality and performance, the great new features, etc. Another reason we are so optimistic is the availability of new cmdlets. There are so many teams doing so much good work with PowerShell that it would spin your head. Unfortunately - it is there news to tell not ours so we can have to bite our tongues and can't say anything. We'll know that the Pre-Beta is out, we had Dan Harm...
PDC Day 1
I love the PDC. You meet a ton of great people, see a ton of great technology and have time to think about how to take your game to the next level. The big announcement was Windows Azure (I don't know about you but when I say that, it makes my mouth feel funny). I thought Ray Ozzie did a good job explaining Azure as a new tier of computing. Windows as an platform to enable seamless experiences across a broad range of devices: phones/pdas, laptops/desktops/workstations, servers/clusters, web/cloud. Scott Hanselman's session really demonstrated the value of this ...
NY Times Delcares PowerShell to be 30% of the value of Windows 7 :-)
Wow - the NY Times is Johnny-on-the-spot with their analysis of the 10 best features of Windows 7 for IT Pros HERE. It turns out that PowerShell is responsible for 3 of them! Come review time, I'm telling my boss that we're responsible for 30% of the value of W7. :-) !!! Just to be clear - I'm totally joking. Windows 7 is an awesome release. It has a ton of great stuff in it. PowerShell IS awesome but it is a tiny just one of the huge wave of improvements. You'll decided for yourself but we are all extremely proud and optimistic about W7. Check it out:...
Another Great Don Jones Video Demo
This month's TechNet magazine has a great video demo from Don Jones where he uses WMI to generate a simple Software Inventory Report. The great thing about Don is his awesome ability to break things down into a series of simple steps. He does this by using Get-WMIObject from the command line and then goes through a series of scripts to illustrate various techniques that give you better and better results (more power, better composability). If you are an advanced scripter, you probably already know the techniques that Don is illustrating but this is a must see for people starting scripting - it ...
Emit-XML
I was writing a demo yesterday and needed a quick and dirty way to generate some XML so I wrote the function below. This highlights a couple of changes that are coming up in CTP3 that I thought I would preview. 1) The keyword "cmdlet" is going away and we'll just have "function". Notice that now you can specify the [Parameter()] attribute on parameters. When you do that, we treat the function like a cmdlet.2) Here-strings can now NEST! Look at how simple the code becomes when you do this. I think you are going to find this to be one of the mo...
GoGrid Snap-in – Managing Cloud Services with PowerShell
I was pleased to see Mitch Denny’s announcement and demo of a PowerShell snapin for GoGrid. GoGrid is a cloud-based, multi-tier grid hosting service leveraging virtual machines. The snapin is a shared source effort at CodePlex (there are now 52 PowerShell CodePlex Projects). Very cool stuff. What could go better together than cloud computing and PowerShell? At the end of the day, cloud computing is about managing at scale in a lights out fashion and end-administrator self-servicing. PowerShell is great at both of these and, as you’ll see at the PDC and our next CTP, PowerShel...

PowerShell’s Security Guiding Principles
One of most common issues we face with PowerShell comes from users or ISVs misunderstanding PowerShell’s security guiding principles. At a high-level, it seems to all make sense – execution policies help ensure that you only run scripts that you trust on your system. These protections are driven by PowerShell’s three main security features. For people that will never use PowerShell, that trust decision is made for you by way of PowerShell’s default “Restricted” execution policy. Others may want to use a verifiable identity chain as their important guiding factor, in which case the Authenticode signing certificate...
PowerShell and JAOO

I'm honored to be invited to talk about Windows PowerShell at a language conference because it allows me to start the process of setting the record straight regarding PowerShell as a language. People parse the world according to their past experience. What that means is that a lot of people have pu...

Decision Input Requested: -EQ with Characters
We are struggling with whether or not to make a change in our comparison operators and would like feedback from the community. Here is the documentation about comparision operators: All comparison operators are case-insensitive by default. To make a comparison operator case-sensitive, precede the operator name with a "c". For example, the case-sensitive version of "-eq" is "-ceq". To make the case-insensitivity explicit, precede the operator with an "i", for example, the explicitly case-insensitive version of "-eq" is "ieq". Here are examples of the current -EQ semantics: PS> "...

OnTap provides a functions to manipulate NetApp servers using the OnTAP web service APIs. I’m not a NetApp user but I was interested in what he was doing and was delighted to read his code. It is an excellent example of PowerShell coding practices and has a number of excellent and clever techniques in it. I LOVE Adam’s code – it is logical, clean and visually coherent. You should view it in an editor that does syntax coloring (lik...
A Thousand Things 1% Better
One of my all time favorite books is The IBM Way by Buck Rodgers. (Actually make that "all time BUSINESS books", it's not in the same league as Discourse on Method or Thus Spake Zarathustra.) One of my favorite statements Buck made was something to the effect of, "products of true enduring quality are not those that do 1 thing 1000% better but rather those products that do 1000 things 1 % better". In other words, details matter. We tried to cover as many details as we could with V1 but frankly we covered so much ground that some things were not a crisp and clean as we...
RDP File Generation/Use of HERE-Strings
Over on the Everyday Nerd blog, I found a great blog entry you should read: Create multiple RDP files with PowerShell. He describes his environment where he has to manage a large set of servers using Remote Desktop (RDP). Having to configure the RDP settings each time he connects to the server, he decided to automate the process by writing a script which generates the RDP files for him. The script itself is cool but the think I wanted to highlight was that the script is a great illustration of a very powerful scripting design pattern. It uses: This pattern has a numb...
Hate Add-Member? (PowerShell's Adaptive Type System to the Rescue)
Do you hate Add-Member as much as I do? Wait - maybe you aren't familiar with Add-Member or the glory of PowerShell's Adaptive Type System. (ATS). When I looked at the .NET type system, my reaction was "....almost". I'm not trying to throw a rock at .NET - anyone that knows me knows how much I love .NET but the reality is that it's type system "almost" meets the needs of a management system ... but doesn't. That is why we invented the Adaptive Type System. There are 4 main components of ATS: Type Adapters. A lot of technologies implement their own type systems within .NET.&nb...

PowerShell vs TSQL & Why Learn PowerShell
Dan Jones has a great blog HERE explaining why the SQL team decided to support PowerShell when they already had T-SQL. It originally started as an email thread responding to the question posed by an MVP. This was a great question to ask. In many ways, PowerShell is merely trying catch up to what the SQL team has been doing for years but do so in a way that everyone can participate. As you'll see from Dan's blog, we did it in a way that it made sense for the SQL team to embrace it. Let's be clear about how what an awesome standard the SQL team set. ...

Some WMI instances can have their first method call fail and get-member not work in PowerShell V1
Due to a problem retrieving the available methods in V1 that we have worked around for the upcoming version of PowerShell, you might experience that the first method call to a WMI object fails with a message that mentions: Exception calling GetType() with “0” argument(s): “You cannot call a method on a null-valued expression.” This happens when calling the first method in objects that are not in the root\cimv2 like: $instance=([wmiclass]"root\MyNamespace:MyObject").CreateInstance() &n...
When NOT To Use "WHERE"
I've seen a number of scripts that look like this: GET-XXXX | Where {$_.name -eq "foo"} or GET-XXXX | Where {$_.name -like "A*"} Whenever you see code like this, it is a sign that the GET-XXXX is not designed correctly. (NOTE: GET-XXXX is NOT a porn retrieval cmdlet - it is a standin for any GET-<SOMETHING> cmdlet). The whole point of a cmdlet is to think about the USER and deliver the correct experience. As a GENERAL rule, we encourage cmdlet developers to leverage PowerShell utilities like WHERE, SORT, FORMAT, etc and NOT to put that function into their cmdlets.&...

Invoking PowerShell from VBScript (COM)
There are a number of scenarios where you might want to call PowerShell from VBScript. You might already have an VBScript that does some function and you want to update it to include some PowerShell operation but don't want to convert the entire script to PowerShell. You might have some people on your staff that are very comfortable with VBScipt and aren't ready to put it down and do everything in PowerShell. You might have a management tool that is hardwired to invoke VBScripts and doesn't know anything about PowerShell (yet!). These are some of the scenarios we thought about...

PowerShell ASP – Too cool!
For the longest time, people have been asking me when they'll be able to use PowerShell in ASP. It makes perfect sense - PowerShell is a great language that let's you do amazing things quickly. Sadly, my answer has always been: At Microsoft, to ship is to choose. We are trying to solve the problem of administrating and automating Windows and until we get things like Remoting, Jobs, Eventing, etc done, it would be a breach of our responsibilities to pursue ASP programming no matter how cool and useful it would be. Now let me be clear, I believe ASP programming is SUPER useful to Admins (as well ...
Dude, Where's My Manual?
Windows PowerShell comes with a lot of help files and documents, but, somehow, my favorite and most-frequently-used help is the help that I get by typing "Get-Help" in the console. And I have always wondered why this help is not readily available as a single document, ready to be viewed, searched, and printed. Well, now it is, with this simple Get-Manual script. This script merges all of the about_* help content with cmdlet help, and puts it into one pretty formatted Microsoft Word document (.doc). Once you have this document, you can search it for specific content. Or, you can print i...

Shay Levy has a review of the latest/greatest IIS PowerShell provider CTP2 HERE. In that review, he shows how you can use Get-Command to show all the cmdlets in a snapin. That works great but produces a linear list of cmdlets. I think the following produces a easier way to digest the information: function Show-SnapinCmdlet ($snapin, $column=6){ Get-Command -PSSnapin $snapin | sort Noun,Verb | Format-Wide -GroupBy Noun -Property Verb -Column $Column } Give it a try and see if you like it.

SQL Use of MiniShells
The SQL team has been receiving a lot of bashing lately over some of the decisions they made integrating PowerShell into SQL 2008. I thought I would take a couple minutes to clarify a few things, eat some sin and talk about a constructive engagement model between the community and the feature teams implementing PowerShell cmdlets. First let me declare my long standing admiration for the SQL team. Those superstars have consistently been one of the teams that really GOT what it meant to release software for production environments. They have a great quality culture and process and they have top-sh...

Windows PowerShell Virtual User Group Meeting #6 – June 24th.
Marco Shaw is hosting the 6th PowerShell Virtual User Group meeting on June 24th. (See http://marcoshaw.blogspot.com/2008/06/windows-powershell-virtual-user-group.html for details and sign-up). He has graciously allowed Wassim and I to present some of the new post-CTP2 things that the PowerShell team is working on. This should be an excellent opportunity to see the latest and greatest and also to provide us with feedback on these new features. I'm going to be talking about the new Modules feature in PowerShell V2. Modules are essentially a replacement for the old V1 snap-in concept. We haven't talked a lot about...
Push-Noun
We looked at a lot of CLI models when designing PowerShell. One of them was netsh. One of the things I had a love/hate relationship with was netsh's use of context. In netsh, you can set context via navigation and then you don't need to provide that context on the command line. For instance you navigate into the FIREWALL and then you perform a set of operations and you don't need to say that you are working on the firewall because it picks it up from the context. I thought I would experiment with this a little this morning. I don't know if this is useful or not but it shows a couple...
PowerShell V1 and V2 Running On WS08 Server Core
Yup- that's right. Check it out at superstar Karl Prosser's blog HERE. He even has a video of it working.

When Will PowerShell V2 Ship?
By far, the most frequently asked question at TechEd 2008 was, "When will PowerShell V2 Ship?". We are expressly prohibited from answering that question and I know that that can be frustrating. I can say this: We are now feature complete with V2. History has shown that when we reach this stage of development, it takes us a year, plus or minus a quarter, before it is generally available. Let me be quick to add that past performance is NOT an guarantee of future performance. At the end of the day, we have an extensive quality process and the community lets us know when it is ready...
Windows, PowerShell and WMI – Unveiling Microsoft's Best Kept Secret

Explaining Objects To Non-Programmers
One of my favorite TechEd 2008 talks was Ben Pearce's talk, "Windows, PowerShell and WMI - Unveiling Microsoft's Best Kept Secret". It was a great talk all up but the one thing I walked away saying, "I've got to steal that", was Ben's explaining of Objects. Anyone that has every tried to explain PowerShell to friends or co-workers will inevitably come across a look of fear and panic when you mention the word "Object". I've seen it hundreds of times. I explain how objects actually simplify the problem but after seeing Ben's talk, I realized that the problem might be that some people don't even kn...
Working With Web Services (Post CTP2 V2 Feature)
Let me start by first apologizing for sharing some information that you are not going to be able to go out and try right away. During one of the interactive Q&A sessions at TechEd, people asked about working with Web Services. I referred to a feature that we were working on and then Hal Rottenberg asked me to blog about some of the details. I'm not sure that this is a good idea because while we have it coded up and in the nightly builds, that is not a guarantee that it will make it into the next version (we often have to cut features in order to create bandwidth to increase the quality of ot...
Block Comments in V2
Smith Catar was looking at my Tech Ed demos and noticed that I used block comments. These are not in the CTP that you have so I guess I sorta let this one leak out. Yes - V2 will have BLOCK COMMENTS!!! Block comments start with "<# and end with "#>". e.g. <# This isablock comment#> Happy happy. Block comments - you asked for them, you'll get them.

Yes, But What About The FLAVOR?
Kirk Munro posted a blog entry HERE saying how thrilled he was at level of presence PowerShell had at TechEd 2008. It was a VERY good TechEd for PowerShell. There were lots of breakout sessions, lots of hands on labs and interactive Q&A, lots of vendor support in the exhibit, lots of books, quite a few mentions in keynote demos and presentations. That was all great but what impressed me the most was the number of people that said how PowerShell had saved their butts, made them heros with their peers or allowed them to do things that they could never do. It reminded me of this great...

PowerShell Eventing QuickStart
The second CTP of PowerShell V2 (CTP2) introduces another new feature called PowerShell Eventing. PowerShell Eventing lets you respond to the asynchronous notifications that many objects support. We didn’t get a chance to fully document these cmdlets in the CTP2, though, so here’s a quick start and primer to help you explore the feature. Discovering Events Before playing with PowerShell eventing, you’ll probably want to find an object that supports events. But how do you know what an object supports? You will most commonly discover this through API documentation ("To receive notifications, subscribe to the...

V2: Custom Enums
Once again MOW proves what a clever guy he is. Check out his blog entry PowerShell V2 CTP2: making Custom Enums using Add-Type. He shows how you can make your own enums using a very simple function he wrote (Add-Enum) which leverages our new Add-Type cmdlet. Wonderful stuff. Add-Type is one of those huge game-changing features that we've added to V2 and it will take all of us a while to understand the full range of scenarios that it enables. The things that we had in focus for this were: We had a couple others but these were the biggies. There is an important aspect to Add-Type that y...

WPF & PowerShell – Part 7 (Sharing Hosts)
Well here we are at the end of a week of WPF. We've learned how to create basic, simple user interactive interfaces. We've seen a brief glimmer of the golden UI layer that is WPF, and have seen how we can use PowerShell to add easy interactivity to XAML. You've seen tricks to help you work your way through .NET code, and help you unwrap the mysteries of WPF. We've seen how we can use PowerShell's list processing technology allows for simple binding to WPF's controls, and how WPF applets can help you present a simple front ends to PowerShell functionality. We've gotten a very brief taste of...
WPF & PowerShell – Part 6 (Running Functions in the Background)
For the next part in the series, I've introduced another update to the Show-Control function you first met in Part 4. In this update, I've added the ability to run the control you've created in a background runspace as a switch. In order to do this, Show-Control employs a neat little trick. It actually creates a background runspace, uses Get-Command to find out its own definition, and packs itself into the runspace it just created. Then it removes the switch parameter that told it to run in the background, but adds every other argument. It also makes sure to recreate the event handlers tha...
WPF & PowerShell – Part 5 ( Using WPF & PowerShell Modules)
In the last post we met XAML, and I gave you a core function (Show-Control) that will help you make interactive WPF controls quite nicely in PowerShell. You can see that, by using Show-Control, it is possible to reduce the size and complexity of a script that creates UI. Today, I'll show you how to build small applications by building functions and modules you can use later. But before we get into that, I'll explain some more of the benefits I see of using scripts to produce user interfaces: Let's focus on the 3rd benefit as we build up a few controls that rely on each other. First, let's ma...
PowerShell and WPF: WTF
A number of people are confused by the WPF/PowerShell series and are "asking WTF?". Aaron has a blog entry, WPF and PowerShell Series - I don't get it. Caywen left a comment on the first in posting saying, "Ugh, I could make a peanut butter and squid sandwich, but that doesn't mean you should." (I like the visual on that one!). I thought I would take a couple of minutes to explain a couple of points and provide some context. PowerShell is NOT a CLI I bet that one took you by surprise. Yup - it's true PowerShell is not a CLI. PowerShell is an AUTOMATION technology. Cmdl...
WPF & PowerShell — Part 4 (XAML & Show-Control)
We're not halfway through our week of WPF, and I'm pretty sure at this point that you have an all right grounding in the basics of WPF & PowerShell, but so far, the scripts haven't really been very much like most PowerShell scripts, and the UIs have not been like most WPF UIs. The scripts have been a little odd because they haven't really made use of a common convention of PowerShell... the pipeline. The WPF examples have also been a little verbose because they do not include any XAML. XAML is an XML format you can use to write user interfaces that use WPF. Because WPF is very property...
WPF & PowerShell — Part 3 (Handling Events)
So far, most of the wpf and powershell scripts you have seen have seen just show you something, but don’t do anything that interactive. However, In order to make real applications you need to be able to handle events. Luckily, PowerShell can make that pretty easy. It is possible to cast a script block to an event handler. The script block has two variables: $this (which is the sender), and $_, which contains the event arguments. Here’s a simple example of using this to click a button: $window = New-Object Windows.Window $eventHandler = [Windows.Input.MouseButtonEventHandler]{$this.Close()} $w...
WPF & PowerShell – Part 2 (Exploring WPF (and the rest of .NET) with Scripts)
In my previous post, I showed you how to create “Hello World” scripts using Windows Presentation Foundation (WPF) and Windows PowerShell. While “Hello World” is relatively easy to write with WPF, it is only the tip of the iceberg of the types of quick user interfaces you can write. Windows Presentation Foundation provides an amazing array of controls for an incredible array of purposes. Out of the box, with just one control, you can: · Show a listbox · Play a video or audio file · &nb...
WPF & PowerShell – Part 1 ( Hello World & Welcome to the Week of WPF )
Welcome to the Week of WPF. During the next 7 days, I’ll help show you how you can use WPF and PowerShell together. PowerShell could always script almost everything in .NET, but, prior to the recent CTP2 you could not script Windows Presentation Foundation (WPF) in PowerShell. Now you can script everything that WPF can do within PowerShell. This means you can write pretty sleek looking UIs in nice little PowerShell scripts. There are a lot of things you can do with this capability, but let’s start things off simple. Windows Presentation Foundation (WPF) is a set of .NET libraries for making next-gene...
Strict Mode: V1 Debug Tool V1 / V2 Best Practice
When we designed PowerShell we decided that we wanted to have Shell syntax and semantics because this is what was missing from the market and because it supports the ad hoc development practice that is so suited to the needs of administrators. We also observed that most shells ran out of power pretty quickly and people had to throw away their scripts and start from scratch with a more powerfull scripting language like Perl. Sadly, sometimes those environments ran out of power as well and people had to throw them away and start from scratch using a systems programming language like C++. ...
The Future Is Here Today
Would like to see what a PowerShell V2 world would look like? If so, check out Jaykul Bennett's Select-Grid script HERE. Here is what impresses me so much about this: Imagine hundreds, thousands, tens of thousands of other 200 line scripts with similar power. Imagine people taking this base script and adding 10 more lines to to things just they way they need them to be. The might not have been able to write the script from scratch but it is not that hard to add 10 lines to an existing script.Now imagine that have a graphics friend and you ask them to replace the WPF with something b...

Superstar Dmitry Sotnikov has done the world a great service today by documenting how to get PowerShell running on WS08 Server Core HERE. Just to be clear, this is not a MSFT supported configuration. That does NOT mean that we think it won't work. What it means is that if it doesn't, you have to leverage the community to help you figure it out instead of Microsoft support.

I HIGHLY recommend this as a great use of 7 minutes of your life (or as Doug points out, you can type Ctrl-Shift-G to speed it up and it will be a great use of 4-5 minutes of your life :-) ) In the demo, he starts out writing and running some C# code.

Fun with Script Cmdlets
Script Cmdlets are one of the coolest things about the newer version of PowerShell. A Script cmdlet allows you to use all of the variety of cmdlet parameter sets inside of PowerShell functions. Since Script Cmdlets are PowerShell functions, and the PowerShell engine prefers to run functions rather than commands, you can use Script Cmdlets to override an existing cmdlet. You might want to do this to add or remove parameters from a cmdlet you use often. Also, you might just want to see what a cmdlet’s parameters look like in a script cmdlet, so you can go write your own. Luckily, Powershel...
PowerShell Transactions QuickStart
The second CTP of PowerShell V2 (CTP2) introduces full engine support for transactions – groups of actions that can be finalized or undone in an all-or-nothing way. Wikipedia gives a great overview of transactions here: http://en.wikipedia.org/wiki/Database_transactions. We put a ton of thought into how to expose this normally developer-centric concept in a way suitable for system administration and system administrators. We would LOVE to hear your feedback on what concepts or behaviours make sense, and especially which ones do not. We didn’t get a chance to fully document these cmdlets in the CTP2,...

How Could You Top CTP1?
(Did I give it away by putting the "1" next to the CTP?) Well put your seatbelts on baby because CTP2 is in the cooker and will be available sometime soon. I'm writing this note to remind everyone of what a CTP is and is not. The original CTP: Watch this Space blog is worth re-reading. Wait, let me be more precise - go read that blog again. Do you remember PROMISED that we'd listen and act upon (a subset of) your feedback and that that meant that things would change? Well we got some great feedback and have made a bunch of changes. I think you are going to ...
Management & Services Division (MSD)
We recently did a short internal "who are we" video about our organization (MSD). I don't know how it got out into the wild but you can check it out over on YouTube HERE. It's 3 minutes, fun and there are a couple scenes of me saying things that are either really stupid or really clever. (seemed clever at the time but upon viewing ... well... :-) ) Jeffrey Snover [MSFT] Windows Management Partner Architect Visit the Windows PowerShell Team blog at: http://blogs.msdn.com/PowerShell Visit the Windows PowerShell ScriptCenter at: http://www.microsoft.com/techne...
$MindWarpingPower = $Cmdlets + $ScriptBlock_Parameters
A while ago I blogged about the power of Flexible Pipeling Scriptblock parameters. The mechanics of this are quite simple: In a pipeline environment, if you provide a SCRIPTBLOCK to a parameter which does not take a SCRIPTBLOCK or an OBJECT, the PowerShell engine assigns the current pipeline object to the variable "$_", runs the scriptblock and uses whatever value it returns for the value of that parameter. Looking back at this, I don't think we've done a good enough job explaining it or promulgating its use because it is incredibly powerful and I just don't see it being used...
WMI Object Identifiers and Keys
Recently one of MVPs, Darren Mar-Elia (Group Policy Guru from SDMSoftware [which as a set of FREE PowerShell GP cmdlets HERE]) was working with our WMI type accelerators and got the following error: $ld = '\\sdmlaptop1\root\cimv2:Win32_LogicalDisk.Caption="C:"' $disk = [WMI] $ld Cannot convert value "\\sdmlaptop1\root\cimv2:Win32_LogicalDisk.Caption="C:"" to type "System.Management.ManagementObject". Error: "Invalid object path " At line:1 char:17 + $disk = [WMI] $ld <<<< This is a great opportunity to discuss WMI Key properties. WMI is an awesome piece of infrastructure. It has a ri...
PowerShell Running Inside of Emacs
Dino Chiesa has a couple of blogs showing how he was able to get PowerShell running as an "inferior shell" within Emacs. Apparently "inferior shell" is an emacs term of art and not a dig at PowerShell :-). I've always respected the all consuming nature of emacs and the love it has from its users. I used to joke that "emacs isn't an editor, it was a way of life". Emacs lovers log into emacs and that is where they hang out - all day. They can do almost everything from within emacs. Well know Dino shows how they can hang out in emacs and run PowerShe...
IIS 7.0 PowerShell Support
Quite a few people have expressed disappointment about the lack of IIS cmdlets or namespace provider. It's been a long sad tale. It turns out that the IIS team (and Sergei Antonov in particular) was one of the first groups to truly "get" PowerShell. I can't tell you how many teams, in the early days, looked at us like we had a rat's tail hanging out of our mouth. The IIS team embraced PowerShell early and did a great prototype of a namespace provider. Actually, now that I think about it, I think they were the first group to ever do a namespace provider. Things...
