Windows 10: How to prevent repeated keystrokes on Windows On-screen Keyboard for Limited Mobility User?

Hi all,I'm helping a family member with limited mobility who is using the Windows on-screen keyboard. The problem we're encountering is that when he clicks on a letter, the system sometimes registers multiple keystrokes instead of just one. Due to his condition, he tends to hold the click for longer than usual, causing repeated inputs.We've tried adjusting the Filter Keys settings in Windows, but it only works on a physical keyboard which he's unable to use. Is there a way to configure the on-screen keyboard to prevent this repeated input when holding a click for too long? Hope you can help an

Wireless mouse lag and keyboards repeating keystrokes.

And the repeated keystrokes problem is not seen in the touch keyboard and on-screen keyboard.

 

keyboard randomly repeating keystroke when plugged in

My keyboard keep randomly repeat my keystrokes. Any key could be repeated, sometimes twice, sometimes 3 times or more, no pattern at all. When I remove the keyboard and plug it in another computer, it work just fine. The built-in keyboard of the laptop also have no issue. Also, it ONLY happens when I have the laptopp plugged in to a power source. If I run it on battery power, nothing is out of place.

I've tried restarting the computer, enable filter key and changing the delay setting for the keystroke, physically removingg the battery, reinstall the keyboard driver, drain the battery completely then hold the power button for more than 30s to drain the remaining electricity before replugging and turning the thing on... but nothing work! The only way for it to work like normal is to unplug the laptop and use it on battery, which is highly disruptive to my workflow.

Could someone help please?

Keyboard Keystrokes no response

Keyboard keystrokes don't work or take repeated input and then repeat multiple times. This starts happening when unlocking the Toshiba laptop.
