Sets SetAutoRestartNotificationDisable = 1 so Windows stops showing the recurring 'your device will restart to finish updating' toast. The update still installs on your next manual reboot; you just stop being nagged. Reversible.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
