Windows: If you use multiple OSes or just prefer using an Apple keyboard you'll know that many keys such as print screen, volume control, and eject do not work in Windows. Apple Wireless Keyboard Helper is a free executable program that restores many of these key combinations.
Even though the name of the program includes wireless it also works on wired Apple keyboards. After running the program these combinations will be accessible in Windows:
F3: PrintScreen
F4: Task Manager
F7-F9: iTunes control
F10-F12: System volume Control
Eject button toggles Fkeys/Functions.
Fn + F key triggers function (useful when in F keys mode)
Fn + Backspace = Delete
Fn+ Eject: Eject CD
If you ever use an Apple keyboard in Windows you should definitely give this little program a try.
