Fix Unexpected Shutdowns or Restarts in Windows 10 or 11

Answer
Record the stop code, remove recently added hardware, install Windows and driver updates, and use Safe Mode or recovery only if the restart repeats.
Confirm the symptom and protect the current Windows state
Record the Windows build, affected app or device, exact message, and the last change before the symptom began. Save open work, keep installers and recovery credentials, and create a current backup or restore point when the supported recovery may change apps, drivers, partitions, or system files. Test one supported change at a time so a useful result can be attributed and reversed.
Start with the supported check
Note the stop code and any named module before Windows restarts.
Apply the current setting
Disconnect recently added nonessential hardware and check Device Manager for warning icons.
Test the result
Install Windows updates, keep adequate free space, and use Safe Mode to isolate repeating failures.
Escalate safely
If the same failure continues, use the recovery option that matches the cause rather than a generic repair utility.
Verify the intended result before broader recovery
Repeat the exact task described by “Fix Unexpected Shutdowns or Restarts in Windows 10 or 11” with a harmless test. Confirm the affected app, account, device, file or setting now matches the Answer, then recheck it after one fresh session or restart when that is part of the supported workflow. Keep the original data and recorded starting state until the result is stable; if only one component still fails, keep further recovery limited to that component.

If it does not work
- If restarts continue, record the time and Event Viewer or reliability entry, then compare Windows Update restart scheduling, temperature, power and a clean boot. Back up immediately if storage or hardware errors appear; do not disable updates or automatic recovery merely to hide the symptom.
