How to disable stop Windows 11 automatical update permanently?

The cleaner approach is to control update timing, not break Windows Update completely. On Windows 11 Pro or Enterprise, open Group Policy and set Windows Update to notify before download or schedule installation at a predictable time. You can also set a Target Feature Update version so the PC stays on the current feature release while still receiving monthly security fixes. On Windows 11 Home, use Pause updates for short breaks and set active hours so restarts do not interrupt work. I would avoid disabling Update Orchestrator or core update services, because that can also affect Store apps, Defender intelligence updates, drivers, and repair operations later.
