To test fast startup:
- Click "Shut down" from the Start menu
- Manually power on the machine back
- Open Task Manager, go to the Performance tab, and click on CPU. If the up time:
-- Resets: Fast startup is disabled, Windows booted from a full shutdown
-- Continues: Fast startup is enabled, Windows didn't fully shutdown previously

I hope Windows 12 will not have feature disabled in this video. This horrible feature should be removed altogether.
