Windows 10: My function keys are not working for the volume and the brightness level.

My function keys are not working for some reason. I usually use the volume function keys and the brightness level function keys, F3 F4 F6 F7 but none of them are working. I had this problem before, and when I asked for help I found out its because of the update. I updated everything but still not working. I need help please.

Changing brightness is no longer smooth with function keys on 1903

Hi, There's a the slider for brightness at the bottom of the Action Centre (build 1903).

If you'd be prepared to consider an alternative... how about smooth control of brightness using your scroll wheel?
Press a key, plus scroll, and adjust your brightness.

The key and the steps are your choice.

Oh, and it can adjust volume similarly.

Works nicely on my Lenovo Thinkpad, where the Fn key steps for brightness are a bit harsh.

Volumouse (free):
Volumouse - control the sound volume with a wheel mouse

 

Keyboard Volume Keys not working while in-game

I happen to have used the Tt Challenger Pro keyboard in the past, and the volume keys worked flawlessly in every game, so it's indeed a weird problem. I would suggest the same thing sneekypeet suggested, using the keyboard software and assign this function to a hotkey, but you said that didn't work either, so yeah...

 

No volume bar when changing volume level and changing brightness causing lag

Hi Trawel,

We appreciate you for being part of Windows 10.

The option for brightness and volume indicator will automatically show on the Windows graphical user interface.

If you face the issue with volume and brightness indicator settings, it may have caused because you are using the ASUS system utilities. I suggest you to open the ASUS system utilities and disable the volume and brightness
indicator and any other Windows related functionality. It is better to disable the ASUS system utility temporarily and check if it is the cause to the issue.

Please be informed that Microsoft has changed level for volume to show as
horizontal level bar not as vertical bar in Windows 10. Click "speaker icon" on taskbar and volume level will appear.
I hope the above information helps.

Kindly try the below steps to repair any corrupted files of Windows components and check if it helps.

• 
  Press Windows + X keys on the keyboard, select the
  command prompt (admin).
  
• 
  Type the following commands one by one and hit Enter key.
  
  Dism /online /cleanup-image /restorehealth
  
  Sfc /scannow
  

Note: If you are not able to repair some files after performing SFC scan, I suggest you to refer to the point 3 “Windows Resource Protection found corrupt files but was unable to fix some of them. Details
are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log”. Under the section “Run the System File Checker tool (SFC.exe)”
to repair the corrupted files after performing SFC scan.
