Win8.1 can't shut down Problem Solution

Recently installed OSX 10.9 Mavericks for the beloved notebook ThinkPad T530.
After running for a day, Win8.1, which was newly installed for a few days, could not be shut down.
Phenomenon: Every time you click and shut down, it does not shut down. It just closes the screen and logs out the user. Click the mouse again, knock on the keyboard, and then go to the login interface.
Solution:
Control Panel->Hardware and Sound-> Power Options->Change the function of the power button->Change the currently unavailable settings
Turn "Quick Start" “ The front hook is removed.
