HP Recommended
Product: HP Probook 450 G4
Operating System: Microsoft Windows 10 (64-bit)

When I start my system (after I have fiddled with device manager or not) certain keys are non working i.e. C X Y T .  (dot)


NUM Lock is also not working. It stays like this then few of them e.g. C gives delayed response and X works fine or C will start working ok but . (dot) will not work whatsoever

I followed some solutions they tell you to go in Device Manager > View > Show hidden devices > other devices and uninstall/disable Keyboard_Filter_01 

I disabled this driver still did not work. Then I also uninstalled two other drivers under Device Manager > Keyboards  still did not work!

But I have kept the PS/2 driver as once I uninstall it or anything it gets installed (it is of course part of Windows)

How do I get rid of this epidemic? I press c it does not work I press . it does not work  .... this is bad for a 7th gen top of the line laptop from HP
