Windows Management Release Candidate
The Windows Management Framework has put out a release candidate porting some of the management features in Windows 7 to versions of Windows from Windows XP to Server 2008. The management framework includes PowerShell 2.0 and the Windows implementation of WS-Management, which is a SOAP-based protocol for accessing and exchanging management information.
This release candidate was previously only available for Windows Vista and Server 2008, but is now available for Windows XP and Server 2003 as well.
