Have you seen the message
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?”
Automatic Windows updates are very good for computer security. However, when these Windows updates are downloaded and installed on your computer, if the updates require a reboot of your computer, Windows keeps prompting you to reboot your computer.
Now, Windows XP Pro users can disable automatic reboot of the computer after a Windows Update. In order to do that, follow these steps
Disable Automatic Reboot after Windows Update for Windows XP Pro users
With this setting you will be able to specify that after a scheduled Windows update, Automatic updates will wait for the computer to be restarted by any user who is logged on, instead of causing the computer to restart automatically. If this setting is not enabled or not configured, your computer will prompt you every 5 minutes to restart the computer to complete the installation.
