As usual, my Windows XP starts asking me to reboot it after installing new updates. In Vista I can postpone notification for several hours and forget about it, but XP pop ups the notification each several minutes giving me a big chance to shut down the computer and lose my work. 

To turn it off just press Win+R and type the following command and press Enter:

net stop "Automatic Updates"

This will completely shot down the automatic updates till the next reboot. Remember that you still need to reboot your computer after completing the work unit to apply the updates - your computer may be vulnerable before reboot.
