Preventing Windows Update From Rebooting
Here's how to prevent Automatic Update from rebooting your machine:
- Start -> Run
- Type: gpedit.msc
- Expand Local Computer Policy / Computer Configuration / Administrative Templates / Windows Components / Windows Update
- Double-click "No auto-restart for scheduled Automatic Updates installations"
- Select "Enabled", then OK. Close the Group Policy configuration program.
You can also prevent the dialog asking to reboot from appearing too often by enabling the "Re-prompt for restart with scheduled installations" and set the amount of time to a bigger number than 10 minutes.
