Prevent Windows Update from rebooting your PC after automatically installing updates.

If you have Windows Update configured to automatically download and install updates, and one or more requires a restart, it will install the updates and reboot itself. If you don’t want your computer restarting itself occasionally, you can stop the auto reboots with this registry hack.

Hive: HKEY_LOCAL_MACHINE

Key: SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Value Name: NoAutoRebootWithLoggedOnUsers

DWORD Value: 0 = no effect, 1 = do not automatically reboot
