Hp all in one touch enabled device not in device manager

[dcgreen1]

I have followed all threads I can find. I have looked for hidden devices, add legacy hardware, usb device search, command prompts, etc.  My computer is a 10 point touch enabled all in one that had a touch screen when I bought it in 2017 and somewhere along the line in 2018, the touch was lost.  Hp not showing driver availability.  This problem appears to have happened to many owners and I have never found a repair.  Is there a new application in 2020 that will re enable, find or purchase a new driver for an hp pavilion all in one desktop touch screen?

@dcgreen1 Just to clarify, did you check if the issue persists in BIOS? if not I recommend checking if the Touch is working on BIOS screen (Accessed by tapping on F10 while restarting the computer) or if you have issues with the keyboard or unable to reach the BIOS:

I recommend running a hardware test on the touchscreen to be sure since it isn't working in the BIOS, please use the below steps to perform the test:

Hold the power button for at least five seconds to turn off the computer.

Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

On the main menu, click Component Tests.

The Component Tests menu displays.

Touch Screen Test - Quick interactive test to determine if the touch screen is functioning correctly. (This test is currently not available in the Windows version of the hardware diagnostics.)
To run the test, click Touch Screen, and then click Run once.

If the test fail, please capture the 24 character failure ID and revert with the details.

If it works on bios and the above tests pass, try checking if it works in safe mode.

Also, reinstall the display drivers, install the latest updates for the display adapters and BIOS,

if the issue persists,  you could reinstall the windows using the recovery partition or the recovery media to fix the issue.
