MacBookPro Dual Booting Windows7 KeyBoard Help

OK, so.. im not sure if this is the right place to post this but oh well.
So i dual booted my Mac-book with Windows7 so i can play video games on it. Having a problem because i need the f1-f12 keys but all i can get is the brightness and sounds and so on. I can press the Fn key and then use the F1-F12 keys but I cant do that all the time when playing my video games. So my question is does anyone know how to lock the FN key? (I was able to lock it in Mac but i cant when i switch over to windows7)

 

ha! it worked!!! Ty!!!!!
