Keyboard issues after Windows 10 upgrade

Apple Keyboard with Numeric Keypad
Windows 7 to Windows 10 Upgrade
iMac 5K

Hi guys,

Fairly smooth upgrade. After initial install the monitor was posterized and the keyboard had issues. I updated Mac OS to current, created a USB using bootcamp and ran that on the Windows side. That fixed the monitor but not the keyboard.

Keyboard works for basic functions but mac specific stuff like brightness and volume are non functional. Rand the bootcamp .exe from the USB again but no love. Any thoughts?

 

Nice fix. Thank you very much!
