According to the List of fixes that are included in Windows XP Service Pack 3(KB926139), the Windows PowerShell 1.0 English Language Installation Packages for Windows Server 2003 and for Windows XP (KB926139) is present. But, after installing Service Pack 3, Powershell is not there!!! Aren't all hotfixex/updates supposed to be installed by the Service Pack? What did I do wrong? Thanks
