WT41N0 Touchscreen - Disable touch

We have a WT41N0 Touchscreen but we want to disable touch function to use it as a WT41N0 with no touch.

I tried with a reg file like this:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Touch]

"InitialState"=dword:00000004

[HKEY_CURRENT_USER\Software\Symbol\Startup]

"SkipCalibrate"=dword:00000001

And after cold-reboot it works.

The problem is that after that the WT goes in standby, the touch restart to work.
