Brightness Function Keys don't work

[坦丁拉夫罗夫]

Hello,

That seems after upgrading to Windows 10 Creators Update some HP laptops have issues.

One of issues is brightness keys stop function.

In my case Fn+F2 and Fn+F3 key combinations not change brightness anymore under Windows however when in BIOS setting this keys are working fine.

BIOS was updated:

Intel HD Graphics driver was updated also:

Here is Winver screen:

'Generic P n P monitor' was not disabled also.

I would be happy to get this issue fixed. Any suggestion?

Thanks,

Konstantin Lavrov
