Hello I just recently updated to Windows 10 from Windows 8.1 64bit and few days ago i encountered a Critical Process Died error and had to do a system reset to fix the issue, after resetting and reinstalling Windows 10 i noticed that i lost my ability to adjust the screen brightness and the computer acts as if there is no brightness controls.
I have uninstalled and reinstalled the display drivers and updated them as well but still no change, ive also called my tech supports and had them preform a remote assist and had them look at the issue but still no fix was found.
I have read several help forums on this site as well and although good advice, still no fixes worked. The f2 and f3 controls my brightness as well as a button in the notification window (which is now gone) as well as the windows mobility center. But none of these are now working.
IF anyone has any help or advice on this subject, it would be greatly appreciated. Thnk you
