Windows Vista: Prevent Automatic Rebooting From Windows Update

Its very annoying if you leave your computer on at night with unsaved work on it, and come to it in the morning and find that it was rebooted. When new patches are downloaded and installed on your computer by Windows Update (if you have it enabled) this feature will automatically reboot your system. So if you have any unsaved work, you will lose it.

If you want to know how to prevent Windows Update from performing this automatic reboot, follow the instructions below.
Note: This tip requires modifying the Windows Registry so proceed with ]caution, use it at your own risk.
  • Open the Windows Registry Editor, from the Search field under the Start menu, type "REGEDIT" and press the Enter key.
  • Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU (note: you might need to manually create some of these keys.)
  • Right-click an empty space in the right pane and select New > DWORD value.
  • Name the new value NoAutoRebootWithLoggedOnUsers
  • Set the value in the field to 1, press the OK button.
  • Close the registry editor when you're done.
