Windows will not shut down properly

Your operating system does not want shut down properly? This is probably due to a problem related to the power management (APM: Advanced Power Management).

To handle this problem, we must first ensure that the APM is enabled in the BIOS of the computer, and then enable it under Windows:
Control Panel/System/Hardware/Device Manager/ View/ Show Hidden Devices
Then look for the NT APM/Legacy Interface Node and activate it.
Or:
Control Panel> Power Options> APM> See that box is checked.
Otherwise, you may install the new device with the Windows wizard.

Then

Start, Run, type "regedit"
Type Ctrl + F
Search "PowerDownAfterShutDown"
Set its value to 1 and restart the computer.
