PowerShell v3 for Down-level OSs

As most of you probably know, the latest version of PowerShell, PowerShell v3, shipped inside Windows 8 and Server 2012 (including Server Core!). Microsoft has also released versions of PowerShell v3 for older versions of windows. Specifically, you can now download PowerShell v3 for:

  • Windows 7 – both 32-bit and 64-bit. You must have at Win7 SP1 loaded. (64-bit – 15.8MB, 32-bit 11.7MB))
  • Windows Server 2008 - both 32-bit and 64-bit. You must have at Server 2008 SP2 loaded . (64-bit - 14.4MB, 32-bit 10.5MB))
  • Windows Server 2008 R2 - 64-bit only and includes Server Core. You must have at Server 2008 R2 SP1 loaded 15.8MB)

If you’ve been running a beta version of PowerShell v3, then you have to remove it first before installing v3.

To get the various installation packages for your system, go to (the Microsoft Download Centre) and look for Windows Management Framework 3.0. This package has PowerShell V3, and all the necessary plumbing (latest version of WSMan, some new cmdlets, etc, etc, etc.).

If you need to remove the WMF 3.0 package, you need to look for the KB article (KB2506143 for Windows 7 SP1 and Windows Server 2008 R2 SP1; KB2506146 - for Windows Server 2008 SP2)

There’s no excuse – get the latest version today!
