Windows XP users will have to wait until next year for Service Pack 3 after all, Microsoft said yesterday as it claimed a recent press release saying otherwise was "a mistake".

Windows XP SP3, the next major roll-up of security patches and bug fixes for the still-popular operating system, was mentioned twice in a Microsoft statement posted from InterOp on Monday. The release, which touted interoperable protocol efforts between Juniper Networks and Microsoft, said at one point that "Windows Vista supports this protocol today and Windows Server 2008 and Windows XP Service Pack 3 (SP3) will support it as well later this year."

Several bloggers and some news outlets took this to mean that Microsoft had changed the launch date for SP3 from its official timetable of the first half of 2008.
