In Windows 8 Consumer Preview, the sound events for 'Exit Windows', 'Windows Logon', 'Windows Logoff' have been removed. WHY? Why not just disable them (assign no sounds by default?). Why does Microsoft take away customization and think they know what's
best for users?? I want the sound events back! I have filed a bug via the Send Feedback Tool. Please return these three sound events to Windows 8 by RC/RTM or I will be very disappointed.
Thanks for your feedback; I have passed it on to the Sound team as a whole. These were removed for performance reasons; we were looking to speed up the time it took Windows to boot, shut down, sleep, and resume from sleep.
