Applying Windows 10 Touch Screen Changes

Question

I have a script that auto-maps/validates monitor to touchscreen settings. I am updating the registry keys in HKLM\Software\Microsoft\Wisp\Pen\Digimon (like the Windows multidigimon calibration app does) with new/corrected entries when monitors occasionally come up wrong. The script works fine, however, I can't figure out how to apply the settings without logging out/back in.

I am trying to figure out if there is a service and/or process I need to restart to apply the settings. It must be possible because the multidigimon calibration app does just that. Also, it's not the "Touch Keyboard and Handwriting Panel Services"

Answer 1

Restarting dwm.exe is enough. Just kill it and let Windows start it back.
