To change windows xp so the stupid nag screen reminding you to restart you computer doesn't pop up every 10 minutes:
Start your Group Policy Editor
Navigate to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Window Update
Then enable the Re-prompt for restart with scheduled installations and set it as high as it will go (1440 minutes).
Unfortunately you will need to reboot for this to take effect.
Rejoice!
