Start in Safe Mode

Launch Windows with the bare minimum of drivers to diagnose a problem.

1. Hold Shift and click Start → Power → Restart.
2. Choose Troubleshoot → Advanced options → Startup Settings → Restart.
3. After the restart, press 4 (Safe Mode) or 5 (with networking).
4. From a terminal, force access to the recovery menu:

   shutdown /r /o /t 0

   Copy
5. If you ticked "Safe boot" in msconfig, remember to untick it afterwards, otherwise Windows will always restart in Safe Mode.
