Have you ever been sitting at a Windows computer and been informed that an update is available to your OS? And so like a good security-conscious user, you download and install the update, only to be told that you need to reboot for some reason? But then you decide that if you've been running without that update for years, then waiting a few hours until your current work is done shouldn't be a big bother. Except, Windows now pops up a "Restart Now" dialog box every few minutes until you do restart.
I'm sure I'm not the only one who would like to continue running his computer without rebooting. Here's the secret.
Press Windows-R. Type "services.msc" in the box and press Enter. Scroll down the list that appears to the item "Automatic Updates". Right-click that item and choose "Stop". All done. No more notice.
When you do eventually reboot (at your lesiure), the service will restart so that you'll be informed of future updates. But you won't be annoyed for the rest of the session.
