Stop the system automatically rebooting after Windows Updates (Windows XP/Vista) New

Normally Windows Update will automatically reboot the system when you have your system configured to "Automatically download recommended updates for my computer and install them" and one or more of those updates requires a reboot. This settings changes the behavior so when users are logged in the system will not automatically reboot.

This tweak can be easily applied using WinGuides Tweak Manager.
