Windows 7 Hangs on Logoff with Outstanding Media Notifications


Consider the following scenario:

  • System has a keyboard with "Volume up", "Volume down" & "Mute" shortcut keys.
  • During the logoff or shutdown process, you press and hold these shortcut keys at the same time.
The system may stop responding. You will have to use the power button to restart the system.


The problem occurs because a deadlock occurs in LogonUI.exe while waiting on outstanding media notification.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
