Force close PC

[Oldfellah]

Is there a way that when you press the shutdown icon in the menu that windows will close no matter if you have anything open. e.g. I use notepad a fair bit and its usually open in the task bar, I forget that its open and go to log off my PC then my PC will go through the close down stages and so I wander off, when I come to use it again I notice that it hasn't logged off and on the screen there is a notice saying notepad is open do I want to close it and it hasn't shut down Grrrr
I know how to force close programs that wont close before I log off, thats not the problem, I just want to log off and it closes.
