RE: Dojo Challenge: How do you prevent Windows from rebooting after an auto
Two methods are available. One is a little more permanent (unless policies are configured back to default values) meaning it only works with versions that have local group policies. The other works temporarily for everyone else until you find the time to restart your computer at your leisure.
For Everyone...
Navigate to Control Panel > Administrative Tools > Services {or type Services.msc from Run box}
Scroll down to and find Automatic Updates select it (or Automatic Liveupdate scheduler in vista). Click stop the service.
Or you can stop the service with the command prompt: net stop wuauserv
This is not permanent and the service will restart after a reboot. This will stop the reminder window Nagging you every 10 minutes to restart, and thus will prevent you from accidently restarting.
Users with Local Computer Policies will navigate:
Start > Run > type gpedit.msc and enter
Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Update
Here either you will enable 'No auto-restart for schedule Automatic Updates installations' or select and set 'Re-prompt for restart with scheduled installations' to a longer interval in minutes.
