Aspire Touchscreen Problem Touchscreen Puddling what causes this.

24-hour update - no touchscreen puddling.

muddle, confuse, make turbid, and muddy are all good descriptions of what it is like to have one's touch screen become "randomly self-activating". I could add "touch screen miasma" as in "illness" transmitted in the fog of ignorance.

Until a sickness's symptoms, causes, and cures are known and fully understood, we have to put up with descriptions that fall short of describing what is going on.

In my case, the screen starts self-selecting random locations as if it had been "touched" when it had not been touched by me. This sickness comes and goes, when it is there, the computer becomes unusable. Rebooting was a temporary fix, but it did not take long for the symptoms to return.

Then the penny dropped. Remove or render the breeding ground for the disease vector uninhabitable.

In this case, I turned off the touchscreen.

• search either in the general search bar or in the Settings search bar for Device Manager, and expand the Human Interface Devices folder.
• click on HID-compliant touch screen, select the Driver page, select Disable Device, Select Yes to confirm you want to disable the touch screen, and close the Driver window.

Thank you Puraw and billsey 

The "remove and let Windows replace the missing essential app" seems to have been a simple and effective solution.

My fingers do get very greasy (from repairing knitting machines) so I have avoided "touching the screen" to keep difficult to remove view-blocking smudges off my screen.

I am coming around to the position that the touchscreen driver may be susceptible to corruption, which is why the "remove-and-replace" solution works.

I don't have any interest in sorting out which line of code is getting messed up unless someone has the time to lead me through the steps needed to capture a copy of the corrupted app.
