Windows 10 automatically restart the PC whenever it installed updates that required a mandatory reboot in order to finish installed. User can no longer delay or postpone a restart indefinitely. […]
The source Permanently Disable & Prevent Automatic Restart of Windows Update in Windows 10 – Tech Journey [WayBack] describes steps to fix a bunch of scenarios:
- Disable Reboot Task
- Stop the re-enabling of Reboot task
- Group Policy (but people reported that Windows 10 ignores the policy when comes to mandatory reboot required for installing updates)
- Prevent Updates from Installing by forcing your WiFi to act like a “metered” connection
- Prevent Updates from Installing by setting the Configure Automatic Updates setting in your Local Group Policy Editor
- For Windows 10 Home edition (that misses the Local Group Policy Editor) setting the above value directly in the registry
