How do you get Function keys to work on Mac Book Pro running Windows 7 under bootcamp? The Fn keys don't seem to work on my Macbook Pro when it's runnign windows 7 Under bootcamp. I can't turn the volume up or down or mute the sound etc.

I've found articles leading to me to believe that I can do this using the bootcamp entry in control panels but I've had no luck doing this. all it seems to change is whether I have to press the Fn button to get the normal behaviour of the F keys. E.G. whether I have to press Fn and F5 to refresh the page of just F5.

I think there is a driver issue with Windows 7 as people seem to have gotten them to work under XP.
bootcamp.exe should launch upon Login. Sometimes it doesn't or at least it doesn't stay running. You can log out and log back in or try the following, it worked for me:

Open Task Manager and see if bootcamp.exe is running. If not, open C:\Program Files\Boot Camp with Windows Explorer and launch bootcamp.exe.

Function keys will work again.
