Additional Information
If you disable the Apple Keyboard Support driver in Windows, Windows will not recognize extended Function keys, nor the (Fn) key.

Important: Apple does not provide technical phone support for installing, using, or recovering Microsoft Windows. Support is available for using Boot Camp Setup Assistant, as well as installing or restoring Boot Camp software while booted into Windows. Support articles and discussions may also be available on Apple’s support website.
