Windows 7 and Windows Server 2008 R2 have been released to manufacturing. Both of these products include Windows PowerShell 2.0 and its exciting new features, such as remoting, ISE, modules, advanced functions, enhanced WMI support, and a variety of new cmdlets, plus a ton of other features. We are proud of this release.

We thank the PowerShell community, specially our MVPs, for helping us to make a great product.

In the next few months, we will release a downlevel package for installing Windows PowerShell 2.0 on Windows XP SP3, Windows 2003 SP2, Windows Vista-SP1 and Windows Server 2008.

  • I am incorrect after further research of Win7 RTM version of PS.  The executable is still located in v1 folder under system32 but the registry key for PowerShellEngine is 2.0 so it is PS v2.

  • If version 2.0 is installed on Windows 7, why is it installed in the Windows\System32\WindowsPowerShell\v1.0 folder?

  • @Robert & @Jordan

    Yes, the .exe is in the v1.0 folder.  The use of "v1.0" has more to do with the fact that the same version of the .NET CLR is being used even with v2.

    See this post:

  • @Brian,

    To check what versions you have, simply do:

    PS> $psversiontable

  • Can powershell 2.0 run on a legacy IA64 2003 SP2 server?  

  • Installed on Windows Server 2008. PS V2.0 is working very well :)

  • @Janine,

    PowerShell 2.0 CTP3 can run on Server 2003.  The issue is whether you want to use the newer v2 functionality like background jobs and remoting.  Those features will not work until there is a newer RC for this OS.

  • It's available from Microsoft Connect as RC for those that want to test it out.


  • It is not available. Here you can download BITS only

    Where is the PowerShell v2?

  • Look harder, Rade. It's there.

  • RC1 requires removing Powershell (version 1) before installing. As this is one out of many patches on a productive windows system, there is not really a way to uninstall it without affecting system-stability...or does anyone know one?

  • Hi all,

    Searching the web for a download brought me here and I concluded I'd have to wait but I found on the outlook live site ( that it is available from

    But apparently you have to uninstall previous version see

  • I'm suprised this has been released so quietly!  I've been highly anticipating its release just for the ability to have remote consoles wrapped up in to it instead of relying on pstools (psexec).

    If you read the KB article .rtf file, it seems installing over 1.0 is OK, so maybe that's just a 'to be safe haven't really tested it' approach that is known to work with Outlook Live?

  • ...Could you please tell me when we can see the PSv2 for XP & Vista... ...Thank you very much!

  • I see that the WMF has been released. Is there a standalone Powershell 2.0 downlevel release? Thanks,Dave
