Windows 10: Touchpad Erratic after Windows 10 1909 Upgrade ELAN CLICKPAD

I have a HP Pavilion Gaming Laptop 15-cx0xxx. I upgraded it to windows 1909. Initially everything was fine but suddenly, the trackpad became erratic, clicking randomly everywhere, freezing, jumping and all sorts of weird movements. I tried updating drivers, it worked fine initially but became the same after sometime. The external mouse is working fine. When I booted into safe mode, or windows recovery environment, the trackpad was absolutely fine. I don't know where is the problem. I installed updated official HP ELAN drivers and updated them using device manager also. But no luck.


Please help me! I can provide more details also...

Cannot disable ELAN clickpad on Windows 10

I've followed most of the advice on many websites, including this one, and there seems to be no way to disable the Elan Clickpad device on my recent HP laptop running Windows 10 Home, including using the Registry. Can anyone help me further?

Details:

Today the builtin touchpad started functioning again and I can't remember how I disabled it when I first bought this laptop. I use a USB external mouse that works much better. When this touchpad is enabled, I accidentally touch it while typing and chaos
ensues.

Cannot disable ELAN clickpad on Windows 10

The first link should be the key, since it comes from HP, the maker of my laptop.

But it doesn't work, because the rightmost tab of the Mouse Properties dialog box, which should be for the touchpad, has been replaced by the tab for the Logitech Mouse that I use to replace the touchpad.

I've also searched the Registry, and found the control set for the Elan Clickpad device. But there is no key or value to disable it!

The Device Manager has NO options to disable the touchpad, only an option to remove the device. When I select this option and restart the computer, somehow the touchpad device is reinstalled automatically. This has been reported on the Web, with no solutions
posted.

Also, I found an ELAN Service listed. I stopped this Automatic service and set it to Disabled. That had no effect, even though it remains stopped and disabled.

There is no taskbar icon for the touchpad.

There is no Control Panel icon for the touchpad.

Please do not give up but try again. There must be a solution. A clue is that the touchpad was disabled until today, when it suddenly started working again, I assume due to Microsoft's automagicallywonderful Windows Update feature, which runs sometimes in
the early hours of the morning when I'm asleep.

 

ELAN Driver for touchpad -Windows 10

After upgrading to Windows 10 my ELAN touchpad driver has all but disappeared. This means I cannot remove tap to click feature amongst others. Can anybody suggest a way forward ?
