The patch fix issues such as keyboard shortcuts or function keys, such as mute, may not work correctly.

Also, when a computer was configured to display the logon screen on resume and when it goes to sleep, a black screen is displayed. In this case, the only way to restart the computer is to hold down the power button. The patch has fixed this problem.

Updated versions of System Update Readiness Tool for Windows Vista, 7, and Server 2008 were also released.
