keyboard brightness function keys (fn-F8 & fn-F9)

after updating the latest window version, my brightness function keys is not working. What should i do?

Hi Hui16. this is a known bug caused by an incompatibility between the new update and your video device driver . . .

Try rolling that device driver back to a previous version and then restart to see if this resolves the issue.

Microsoft are aware of the compatibility issue and will hopefully release a patch for this as soon as possible . . .

Hi Hui16,

Open Device Manager (accessible by right clicking your Start Button)
Expand the Display Adapters Section
Right click your video card and choose Properties
On the Driver Tab, choose 'Roll back Driver'

Restart your PC once done . . .

If that does not resolve the issue, go to the support page for your device on the manufacturers website, then download and install the video driver they recommend, it may well be an older version to the one you are currently running
