Restart Your Computer
This is an underrated fix that seems to work more often than not. Whenever you’re experiencing technical issues on your computer, your first solution must be to restart your device.
If the issue is caused by a program taking too much RAM and slowing down your device, restarting your computer shuts down all programs and starts afresh. If this method doesn’t work, move on to the next one.
Adjust Keyboard Repeat Delay
The keyboard repeat delay determines the time your computer’s operating system would wait before repeating a keystroke when the key is held down. Adjusting this setting to prolong the delay may work if the double-typing issue is minor. Follow the steps below to change your keyboard repeat delay settings.
