DSC Resource Kit Release December 2016

Katie Keim [MSFT]

We just released the DSC Resource Kit!Since our last release on November 2, we have added 1 new module, AuditPolicyDsc, which allows you to edit your audit policy subcategories and options. Thank you to Adam Haynes for this great new module!

Outside of the DSC Resource Kit, we also recently published an update to GPRegistryPolicy in the PowerShell Gallery. The latest version now includes a DSC resource to help you locally manage policy registry keys.

We have also added two new maintainers to the DSC Resource Kit:

  • Johan Ljunggren (xSqlServer)
  • Daniel Scott-Raynsford (xAdcsDeployment, xCertificate, xNetworking, xStorage)

These guys have shown outstanding dedication to their modules and continue to be invaluable contributors to the DSC Resource Kit. Congrats!

This release includes updates to 17 DSC resource modules, including 5 new DSC resources. In these past 6 weeks, 101 pull requests have been merged and 43 issues have been closed, all thanks to our amazing community!

Update (12/16) – xPSDesiredStateConfiguration and PSDscResources have now also been released! PSDscResources now includes Script, Registry, WindowsProcess, GroupSet, ServiceSet, ProcessSet, WindowsFeatureSet, and WindowsOptionalFeatureSet.

The modules updated in this release are:

  • PSDscResources
  • SharePointDsc
  • xActiveDirectory
  • xAdcsDeployment
  • xCertificate
  • xComputerManagement
  • xDatabase

Our last community call for the DSC Resource Kit was last week on December 7. A recording of our updates as well as summarizing notes are available. Join us next time to ask questions and give feedback about your experience with the DSC Resource Kit. Keep an eye on the community agenda for the next call date.

We strongly encourage you to update to the newest version of all modules using the PowerShell Gallery, and don’t forget to give us your feedback in the comments below, on GitHub, or on Twitter (@PowerShell_Team)!

As with past Resource Kits, all resources with the ‘x’ prefix in their names are still experimental – this means that those resources are provided AS IS and are not supported through any Microsoft support program or service. If you find a problem with a resource, please file an issue on GitHub.

How to Find Released DSC Resource Modules

To see a list of all released DSC Resource Kit modules, go to the PowerShell Gallery and display all modules tagged as DSCResourceKit. You can also enter a module’s name in the search box in the upper right corner of the PowerShell Gallery to find a specific module.

Of course, you can also always use PowerShellGet (available in WMF 5.0) to find modules with DSC Resources:

# To list all modules that are part of the DSC Resource Kit
Find-Module -Tag DSCResourceKit 
# To list all DSC resources from all sources 


To find a specific module, go directly to its URL on the PowerShell Gallery: http://www.powershellgallery.com/packages/< module name > For example: http://www.powershellgallery.com/packages/xWebAdministration

We recommend that you use PowerShellGet to install DSC resource modules:

Install-Module -Name < module name >


For example:

Install-Module -Name xWebAdministration


To update all previously installed modules at once, open an elevated PowerShell prompt and use this command:



After installing modules, you can discover all DSC resources available to your local system with this command:



How to Find DSC Resource Modules on GitHub

All resource modules in the DSC Resource Kit are available open-source on GitHub. You can see the most recent state of a resource module by visiting its GitHub page at: https://github.com/PowerShell/< module name > For example, for the xCertificate module, go to: https://github.com/PowerShell/xCertificate.

All DSC modules are also listed as submodules of the DscResources repository in the xDscResources folder.
