Windows PowerShell™ command-line interface is a new command-line tool and supporting scripting language from Microsoft that complements Cmd.exe in the Windows administration context. In the SharePoint administration context, Windows PowerShell supersedes the Stsadm.exe administration tool. Moving forward, you should use Windows PowerShell scripting technology to develop any new command-line scripts in SharePoint Foundation 2010.
