I have 2 screens, one is touch and one is not. Every few months, Windows gets confused and puts the touch input on the non-touchscreen. I usually spend an hour trying to figure out how to get this back to normal because all of the "fixes" I find with Google are wrong (or no longer apply because of Windows Updates, etc.). Here is how I can get it to work:
- Use the Search on the Taskbar and type "calibrate" and you should see "Calibrate the screen for pen or touch input".
- Everything else I found to solve this problem said to type "Tablet" and look for "Tablet PC Settings." I can't get to this using "Tablet". I do get "Tablet Settings" but this isn't the same thing and doesn't let you change the input.
- Once you get to the "Calibrate the screen for pen or touch input", it will be the "Tablet PC Settings" dialog and there is a "Setup" button in the Configure area:
- Once you get the message on the right screen and tap with one finger, it will be fixed (until the next time it gets confused).
