A number of bugs have been fixed for Windows 7, notably:
• Windows Media Player no longer randomly hangs or displays a black screen after playing VC1 (WMV) video files for over 4 hours.
• Bioshock no longer displays visual corruption with Vsynch and MLAA enabled.
• Transcoding MPEG-2 video to H.264 no longer causes an application crash.

Winows XP on the other hand, has only recieved a single bug fix. A crossfire issue has been fixed so that Civilization V " no longer stops responding during game launch when Crossfire is enabled."
