Permanently Disable Touchscreen
I have about 20 HP TouchSmart 9300 Elite All-in-One desktops running Windows 10 updated to 1909 in service on my school campus and the touchscreens have started to malfunction. The cursor jumps around while in use or even when nobody is using the computer. We have disabled the touchscreen in the Device Manager and it returns later. Yesterday I actually could use the touchscreen while looking at the device manager that indicated it was disabled.
We have also gone into the registry and followed instructions to disable the touchscreen there. It seemed to work for a while, but I came in this morning and my test pc had touch capabilities again. I am baffled.
The computers are still good computers for my environment and I do not need the touchscreen. If anyone has suggestions as to where/how I could try to permanently disable the touchscreen, I would love to here them!
Thanks

Touchscreen migth be set using the Control Panel Mouse/Pointing Device. If not, there should be a Software that manages Touch capabilities.
Have tried disabling driver for the touch screen?
If you have the registry keys you can add them to a startup script or logoff/shutdown script so it disables them on every session.
also in device manager under HUMAN INTERFACE DEVICES you should have an entry for your touchscreen (additional to the one you may have under the MICE AND OTHER POINTING DEVICE, disable that one also, you may have more than one under HID COMPLIANT, be sure to disable the correct one or your mouse or keyboard might stop working.

Looks like you have done your best -- disabling in Device Manager, disabling in the Registry.
a) See if the touchscreen can be disabled in the BIOS. This would be the best solution, as then it won't appear to Windows when it does the startup hardware scan.
b) Open the case just far enough to unplug the touchscreen flat cable (or snip it if it can't be unplugged).

if it keeps re-enabling itself after every reboot, then see if from task manager in the startup tab you have any touchscreen driver that migth be reenabling it, and disable that one.
It is built in and is seen as a hid device. In win10 not sure there is an option to disable it, putting a note, advisory or put filters on the monitors.
Keyboard, with "use me" note.
Potentially screen cleaning or you might need to use the control panel to calibrate the monitor's touch screen.
Much depends when it oct began, possibly a faulty driver update caused this issue.
Check with ?hP support and see if they gave updates that might address this issue.

Well, not configuration we tried worked permanently. In the end, we were able to go in and removed the connections for the touch sensor, They were actually fairly accessible on these units. This saved thousands of dollars for us!
Thanks for all the advice!
