The Powershell team 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 products, so you can now download them from either source. Because Windows PowerShell 2.0 is in-place upgrade to Windows PowerShell 1.0, we will no longer be offering Windows PowerShell 1.0 on Windows Update.

Windows PowerShell 2.0 appears as an option in a Windows Update scan only if the computer meets the following conditions.

• The computer has at least Microsoft .NET Framework 2.0 SP1
• The computer does not have a non-RTM (CTP, Beta, RCs etc.) release of Windows PowerShell. (Windows PowerShell 1.0 RTM can be installed.)
