Microsoft divides its support lifecycle into two phases: “Mainstream” and “Extended.” In the Mainstream phase, software receives free security updates, bug fixes, new or improved features, etc. In the Extended phase, only security updates are provided.
Windows XP and Office 2003 are currently in Extended support until April 8, 2014. After that date, they’ll cease receiving even security updates, leaving anyone still using that software vulnerable to viruses, malware, etc. that are designed to target remaining weaknesses.
Windows Vista and Office 2007 will be in Extended support from now until April 2017.
