On April 14, 2009, Windows XP and its family of operating systems were moved from Mainstream Support to the Extended Support phase as it marks the progression of the legacy operating system through the Microsoft Support Lifecycle Policy. During the Extended Support Phase, Microsoft will continue to provide security updates every month for Windows XP; however, free technical support, warranty claims and design changes are no longer being offered.
Only Software Assurance customers who still run Windows XP can enroll in the Extended Hotfix Support Agreement if they want to receive non-security related hotfixes. The enrollment offer for consumers ended on July 13, 2009.[
