1. Create a new txt file somewhere on your system, open it and put in this one line:
(new ActiveXObject("Shell.Application")).ShutdownWindows();
2. Save and Close the file. Change the extension to js and your got it.
3. You can make a shortcut to that file to make it easy to shut down your system.

Pressing down Alt key press F4(function key). This will shutdown your system... if there are any windows opened you have to repeatedly repeat the same till all the windows get closed..

PS: This shortcut can be used to close the active windows too...
