Windows 10 keeps enabling touchscreen

Question

Hey folks.  I have an Optiplex All-In-One that I keep in the garage for looking up info while I'm out there working on projects, I can't remember if it's a 9010 or 9020, but that probably isn't relevant.  Normally, I have the touchscreen disabled on this system.  The screen sits up high so it's hard to get to, but more importantly, being in the garage, it is also where gnats and other small flying insects can land on the screen.  Probably doesn't sound like a big deal at first, but once the first one lands and lights up the screen, it attracts more insects, who then start clicking on the desktop icons, on the taskbar, opening all sorts of apps and windows, and last night started blaring the speakers in the middle of the night when some radio streaming was 'clicked' on... I don't have a password set up on the system, so there is no lock screen that would normally keep much of this from being an issue.  Being a simple garage system mainly for web browsing, this wasn't needed in the past. In the past, I had simply gone into device manager, pulled up the HID section, found the touchscreen, and set the driver to disable.  Since going to Windows 10, Microsoft has decided to be super helpful, and every time Software Update runs, it enables this driver again for me, and then I have to go back and disable it until Software Update runs again. Uninstalling the driver was equally unhelpful, thanks to Win10 installing it again for me. I can find no system setting to actually let me turn the touchscreen off as a preference setting, so playing with the driver is the best I've been able to do. Does anyone have any suggestions on some way around this?

Guess you're getting back to the original meaning of "bug" in computing. :emotion-4:

What happens if you disable Touch Keyboard and Handwriting Panel Service using services.msc in Win 10? Does that keep the touchscreen from being reactivated all the time?

Well, in my case it's the live bugs that are the issue, not the dead ones. :)

I'll give this a try, but I think that service would only turn off the keyboard functionality of the touchscreen, not stop it from being used as a mouse. I'll set this tonight when I get home though anyway, can't hurt.

I checked that setting on the system, it was already disabled, and touch was still active, in other words the screen was still acting as a mouse.  Looking for any other suggestions.

Maybe you could put some kind of screen-saver film or a glare-screen on the screen that's not compatible with touch.

Want to swap systems with another forum member who can't get touch to work on his AIO after upgrading to Win 10? :emotion-5:
