after installing parallels desktop 11 on mac and configuring my existing bootcamp windows 8.1 installation as virtual machine i am not able to control brightness in bootcamp anymore. i believe it must have something to do with the drivers being installed. the virtual machine on mac works flawlessly but when i change from mac os to bootcamp windows 8.1 i cant change the brightness of the screen anymore (buttons on mac keyboard dont work) already tried uninstalling parallels tools without succes. please help!
