Some time back I mentioned in a comment<\/a> I was working on some PowerShell extensions for Windows Installer. Actually, it was a long time ago and I’ve spent more time learning the “ins” and “outs” of PowerShell<\/a> (mostly the “ins” using .NET Reflector<\/a> because the documentation needs work) than actually writing anything. Then, of course, there was that little Visual Studio 2005 Service Pack 1 project<\/a>.<\/p>\n

While I am still busy working on things for future releases out of Developer Division and beyond, I want to make this project available and add features to it over time. So, I introduce to you the Windows Installer PowerShell Extensions<\/a> project on CodePlex<\/a>. There is no installation package yet as I explore better alternatives to running installutil.exe<\/em> or implementing similar functionality for use in an in-process custom action, but you can download what I have today<\/a> and install it yourself using installutil.exe<\/em>. After installed, start PowerShell and execute the following:\n<\/p>\n

add-pssnapin psmsi\n<\/span><\/p>\n

There are two cmdlets currently provided for enumerating installed and advertised product information, and for enumerating applied, superseded, and obsolesced patch information. I have posted some examples<\/a> and will add more over time. For example, to get the sizes of all applied, superseded, and obsolesced patches, execute the following:\n<\/p>\n

get-msipatchinfo -filter all | get-itemproperty | format-table fullname, lastwritetime, length -autosize\n<\/span><\/p>\n

I’d also like to shout out my appreciation to Sara Ford<\/a> for helping expedite the process of getting this project published on CodePlex.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"
