Thank you so much @david-cslu! You are a life savor!
Totally saved my computer from the trashbin
Glad to help. A word of warning though if you install the latest win 21h update it over writes the registry and this fix.
It will cause chaos if you have a password set as the pulsing bubbles just restart the PC. If no password set just click device manager as before disable the touch screen (dont reboot) all will be working normal just change the reg key again as per instructions. Fix will stay until probably Windows 11 comes out.
Don't upgrade to win 11 with an active password set.
If you have a password set the logon screen section will be black and wont allow you to enter password.
Solution -time consuming keep moving cursor to attempt to enter password, it will turn white, enter first character of password - Important you have to wait for the characters background to go from black to white then enter next character and so on. You will learn to watch the bubbles hover over the bottom r/h corner to enter password characters one at a time.
