Windows Server 2008 SP1 and Windows Vista SP1 now UNSUPPORTED
Ned here with the last word on this: Windows Server 2008 SP1 and Windows Vista SP1 are no longer supported. You must install Service Pack 2 to get updates and support from Microsoft going forward with those OSes. But me no buts.
I made a helpful diagram of how to resolve this - or indeed any - Windows issue.
