Fn not working in Win 7 + BC Control Panel oddness

Hello all,

I am aware this kind of question has been asked many times before so I have tried to do some research for similar posts and solutions but had no luck. The situation is I have recently bought a 5K iMac and then had the task of transferring everything I could from my older iMac, which had a Windows/BC partition and an OS X one. Managed all that fine tho albeit not as straight forward on the Windows side, but that is for another topic. The BC software/drivers I used were downloaded and installed by the BCA as recommended by Apple btw, so I believe are v5.1.7 or so.

The oddness is that when using the Bootcamp Control Panel in Windows is that the Apply/OK/Cancel buttons don't seem to work properly so for example clicking Cancel doesn't close the window, Apply doesn't become greyed out and OK doesn't do either. Yet it does seem (the tick-box remains ticked after closing) to save the setting you chose such as for the Fn keys and also the panel for choosing your startup disk seems to work correctly including the Restart button.

I can't help think that this is related to do with being unable to get the Fn key functions working under Windows (it definitely works in OS X).

Have tried a few things already such as running a repair on the Bootcamp Services program and reinstalling/repairing everything from the USB device I installed Win 7 from, which has the downloaded BC software on it. The only things I haven't tried, which I am reluctant to try without advice as it may cause more problems, is either deleting the Bootcamp program then reinstalling it or reverting to an older version of the software/drivers from the Apple Support site...however the latter I fear would make things worse.

If anyone has come across this before or have any better suggestions then I let me know please 🙂

Thanks,
