Mac keyboard function keys on Windows 10 not working properly

Hi . I hope this helps someone. I used boot camp to install Windows 10 on my 2011 IMAC. Downloaded newest version of Boot Camp drivers and everything was loaded as planned. Except the Apple Wireless Keyboard was not working correctly. I uninstalled the drivers and reinstalled again. Still not working. After 3 days of reformatting and reinstalling Windows 10 I finally found what was wrong. After loading Boot Camp drivers A Qwerty Keyboard is loaded. Go to SETTINGS. TIME and LANGUAGE, SPEECH,REGION ,DATE. Make sure you are in your correct TIME ZONE. Then go to REGION and LANGUAGE . Make sure this is set for your Region etc. Press your LANGUAGE under ADD A LANGUAGE and this gives another BUTTON called OPTIONS and PRESS THAT . It shows ADD KEYBOARD and PRESS THAT. Find APPLE KEYBOARD and load this. Once it is loaded you can remove QWERTY KEYBOARD leaving only APPLE KEYBOARD. Every time you boot into Windows 10 the APPLE KEYBOARD is now loaded. Hope this helps.
