Background: I'm trying to shutdown my Windows 10 PC.

What have I tried

1. Disable "fast startup" in power settings.
2. On the login screen, I'm keeping L-shift pressed while clicking "shutdown". However, it's hibernating.
3. On the login screen, I'm keeping L-shift pressed while clicking "reboot". However, it's hibernating.
4. After logging into Windows, I opened the start menu, and then click "shutdown" while pressing L-shift. However, it's hibernating.
5. After logging into Windows, I opened the start menu, and then click "reboot" while pressing L-shift. However, it's hibernating.
6. After logging into Windows, I executed shutdown /s /t 0. However, it's hibernating.

Solution

Run the following commands

powercfg -h off
shutdown /s /t 0

Now the fucking windows is shutting down.
