Submission + - Service Pack or Die (microsoft.com)

Microsoft is telling visitors that support for Windows Vista without any service packs will end on April 13, 2010. Support for Windows XP with Service Pack 2 (SP2) will end on July 13, 2010. I find it interesting that this message was delivered to a Win 7 box making an XP command line reference inquiry.
