CWmike writes "Microsoft says it won't patch Windows XP for a pair of bugs it quashed Sept. 8 in Vista, Windows Server 2003 and Windows Server 2008. The news adds Windows XP Service Pack 2 (SP2) and SP3 to the no-patch list that previously included only Windows 2000 Server SP4. 'We're talking about code that is 12 to 15 years old in its origin, so backporting that level of code is essentially not feasible,' said security program manager Adrian Stone during Microsoft's monthly post-patch Webcast, referring to Windows 2000 and XP. 'An update for Windows XP will not be made available,' Stone and fellow program manager Jerry Bryant said during the Q&A portion of the Webcast (transcript here). Last Tuesday, Microsoft said that it wouldn't be patching Windows 2000 because creating a fix was 'infeasible.'"
