Sets NoAutoRebootWithLoggedOnUsers = 1 so Windows Update will not automatically reboot the machine to finish installing updates while a user is signed in — it waits until you restart yourself. Updates still download and install; only the forced reboot is suppressed. 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.
