Change the toggle to off to disable it, or on if you want to disable the keyboard in Windows 10. If it’s enabled, as well as “Turn on slow keys…”, it’s likely your issue. Look for the option that says “Use Filter Keys”. In the Settings sidebar, look for the “Interaction” heading and click on “Keyboard” underneath it.
Press the “Start” button, then click the settings cog, above the power button. You may also experience a ticking noise when you press buttons. This setting makes your keyboard wait for up to 20 seconds after a key is pressed before it accepts input. If your keyboard is still frozen it’s possible someone has enabled slow keys on your PC.
