Hello! I just installed Windows 10 on Macbook Pro 7,1 (mid 2010). The FN keys (brightness, volume, etc.) are not working. Also if I try to adjust the brightness of the monitor using Display Options and it doesn't work either. Please help me know how to fix this issue. I'm a new member and I can't post links to screenshots yet. Thanks!
I got this answer from google it might work if you are using bootcamp: Windows 10 Bootcamp Fn Keys not working Boot Camp Answered by Teef21 (Aug 4, 2015) I actually got it working. If you take that USB with the bootcamp and driver stuff on it and open it up, go to this folder, my usb was in the E drive, "E:BootCampDriversApple" and in that folder there is a file called "AppleKeyboardInstaller64".. Just install that and it should work. That is what I did and it works now. I thought I would test this out since I have done stuff like this before too I hope it works for you as well. Good luck!
