Today is Microsoft Tuesday --- the SECOND Tuesday of the month --- on which Microsoft is expected to release its monthly cycle of Windows critical/security updates. Based on previous history, they should become available at 1 P.M. [USA - Eastern Standard Time]
Please use Windows/Automatic Updates to determine which updates are applicable to your particular system.
And as a reminder, there should be no more updates for XP [aside from the MSRT, which Microsoft will continue to provide for XP through July 14, 2015]...
