Howto Remove the Restart your Computer now dialog box

You might have experienced the annoying dialog box if you ever updated your computer. This is the message that appears if you did:

Updating your computer is almost complete. You must restart your computer for the updates to take effect. Do you want to restart your computer now?

This message pop ups at the end and immediatly gets the focus, even if you are in a game or watching a fullscreen movie. You have the option to restart now or later. The first would result in an immediate reboot while the second would nag you again in 10 minutes. This will be annoying if you can´t reboot your computer at that time.

The dialog box can be configured in the following police:

Start / Run / gpedit.msc / Local Computer Policy / Computer Configuration / Administrative Templates / Windows Components / Windows Update / Re-prompt for restart with scheduled installations

You can disable this box at all or define a time period for the reboot later option. You could select every four hours for example or even more if you like. I decided to remove this box completly.

You could also set the following registry key to 1 to recieve the same effect:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\
WindowsUpdate\AU\NoAutoRebootWithLoggedOnUsers
