Disable Windows Update in Windows 10 IoT Enterprise

Disabling Windows Update in Windows 10 IoT Enterprise isn’t just about stopping the service—Windows can restart it automatically. You need a combined approach.

What actually works:

Group Policy (recommended)

Disable Configure Automatic Updates → this stops automatic downloads and installs

Disable Windows Update service + scheduled task

Stop wuauserv and disable related scheduled tasks to prevent restart

Registry policies

Set keys like NoAutoUpdate=1 and block update endpoints to enforce the restriction

Important note

Microsoft recommends controlling or disabling automatic updates via policy, not just killing the service, and ensuring you still have a manual update strategy for security

Practically, most setups use Group Policy + service + task disabling together for full control.
