How can I completely disable tablet functions in Windows 7?

I'm the owner of an HP Pavillion tx2120us tablet PC, which has a known problem of making the cursor jump to the lower right corner of the screen.

I've narrowed the problem down to the pen tablet function, since in Vista I was able to turn the tablet input process down, and the problem seemed to go away. It was a simple matter of just opening the task admin and killing the process.

However, as far as I can tell, I can't find the same process in Windows 7, and I have supposedly already turned the tablet functions via "Start" -> "Control Panel" > "Programs and Features" > "Turn Windows features on or off". Yet after a reboot the screen still seems to react to the tablet pen.

How can I finally turn the darned tablet functions off (while still being able to re-enable them in the future)?

EDIT: I have also turned the service off and restarting, as suggested by outsideblasts, to no avail.

Go to Services (just windows search it) and see what the status is. Set it to manual or disabled. If it already is disabled then I don't know!

You can also turn off the "Tablet PC Components" feature at the command line, by running:

dism /online /disable-feature:TabletPCOC
