Windows XP Service Pack 3

Windows XP Service Pack 3 (SP3) includes previously released Windows XP updates, including security updates and hotfixes. It also includes select out-of-band releases, and a small number of new enhancements, which do not significantly change customers' experience with the operating system. Windows XP SP3 provides a new baseline for customers still deploying Windows XP. For customers with existing Windows XP installations, Windows XP SP3 fills gaps in the updates they might have missedfor example, by declining individual updates when using Automatic Updates, and updates not available through Windows Update.
