PRESS RELEASE

REDMOND, Wash. — March 14, 2007 — Microsoft Corp. today announced the extension of the Xbox LIVE® games and entertainment network to the Windows® platform, bringing together the most popular online console game service with the most popular games platform in the world. Debuting on May 8, 2007, with the launch of the Windows Vista™ version of the Xbox® blockbuster “Halo® 2,� Games for Windows — LIVE will connect Windows gamers to over six million gamers already in the Xbox LIVE community. Then, launching in June, “Shadowrun™� will for the first time connect Windows gamers with Xbox 360™ players in cross-platform matches using a single service. “UNO®,� releasing later in 2007, will also support cross-platform play between Windows and Xbox 360.

The launch of Games for Windows — LIVE marks a major expansion of the Xbox LIVE service across multiple platforms, uniting gamers with a single identity, a single gamertag, a single friends list and a single list of achievements attainable on the Xbox 360 and a Windows-based PC. Games for Windows — LIVE gamers will be able to easily find and play supported titles online with their friends across a Windows computer or an Xbox 360.
