Solution when Windows 8 cannot shutdown

I got a problem on my laptop that I migrated to Windows 8. It could not shutdown. When choosing shutdown the computer ended up running the only way to shutdown was to press the hardware switch for a long time several timed forcing the computer to stop.

I've googled the problem and the solution is:

Right-click the lower left corner to get the power menu, click Power options:

Choose, "Choose what the power button do" in the left column:

Click "Change settings that are currently unavailable":

Uncheck "Turn on fast start-up":

And after this change the computer is possible to shutdown.
