Windows has some really annoying nuisances and this is one of the top ones. “Windows Update” requires a computer restart (reboot) after it finishes installing the updates. It doesn’t care much if you’re working or not, and the postpone button allows only between 10 minutes to 4 hours, and if you postpone it long enough it will start counting down by itself and force a restart. This is a problem if you’re in the middle of important work or you’re leaving your computer to run something while you’re away.
Know this next annoying nag screen?
To disable that until the next reboot goto cmd (click Start->Run and type in cmd or just type cmd in the Start “search program and files” box). Once cmd has opened type in the following command:
net stop "windows update"
If this doesn’t work rightclick on cmd when it shows up and select “Run as Administrator” to make sure it has the right permissions to stop the Windows Update service. (source)
