Touchpad and Brightness control(display driver) not working properly

HP Recommended
Probook 440 G6 Notebook PC
Microsoft Windows 10 (64-bit)

I installed official touchpad drivers from following the official link:


Even after installing driver touchpad doesn't behave as it should. The driver doesn't do anything.

Also, I have installed an intel driver for the same but  I can't control brightness using functional keys.


Please help soon possible.
