Shutdown button (Start Menu & Login Screen) logs out but doesn't shut down in Windows 10 Desktop PC

Solution 1:

To make the shutdown buttons shutdown the PC you have to change some settings in the power options.

1. Navigate to Control Panel\All Control Panel Items\Power Options\System Settings
2. Click on the text which says "Change Settings that are currently unavailable"
3. Uncheck "Turn on fast startup (recommended)"
4. click "Save changes" at the bottom of the screen

Solution 2:

Try editing the Power options; also try shutting down using the shutdown command in the Run dialog Win-R:

shutdown -s -t 00

or, to force shutdown,

shutdown -f -s -t 00

If that works, copy it to a batch (text) file named myshutdown.bat (or any filename with .bat extension); create a shortcut in the start menu for convenience and to make a keyboard shortcut.

You can try the -h (hibernate) option, but it is deprecated, as MS seems to have found it unreliable since Windows 8.

Solution 3:

Starting with Windows 8, Microsoft changed the way how Windows boots to make it faster. This is called HybridBoot and is a logoff + hibernation. Next time Windows starts it resumes the kernel from hibernation and after login it starts your startup tools as in all older versions. To do a full shutdown you have to press the SHIFT key and press the Shutdown button.
