Windows 10: Allowing touchscreen to open on-screen keyboard when touching input fields as well as...

Touch keyboard not working

I have a convertible Laptop with a Touchscreen. I've tried using the Touch-Keyboard but is not working.

In tabelet mode the touch-keyboard doesn't auto-open when clicking on a text input field and when I enable the button in the Taskbar and try to open the touch-keyboard by clicking the button it doesn't work either.

I tried following solutions:

• Setting the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Scaling to 22.5
• Setting the startup tupe of the Touch Keyboard and Handwriting Panel Service to Automatic or Automatic (delayed)

The Registry key didn't exist on my device and creating it didn't solve the issue. The service and it dependencies were already set to automatic and trying to change them to automatic (delayed) didn't work and showed the error message "The delayed auto-start
flag could not be set. Error 87: The parameter is incorrect"

BTW : Use mouse and touch both can't open Touch keyboard button.
The issue cannot be recovered after restart/coldboot.
Rest this PC can recovery it.
