Turned down brightness to zero, can't turn it back up.

Last night I decided to let my game idle while I went to bed. As the computer is in my room and I didn't want the screen light to keep me up I decided to turn down the brightness. So I went to the right side windows 8 menu clicked on settings and pressed brightness. Now I accidentally turned it down to zero and I let my mouse go.

So now my screen is black. This wouldn't be a problem if the brightness buttons work but they don't (didn't install the boot camp drivers)
Is there any way I can recover this? Or would I have to reinstall my pc?

PC specs: mid 2010 13inch Mac book pro, no bootcamp drivers

Try to start Windows in a safe mode and change it there.
