Use Third-party Apps

If you do not prefer or have hands-on experience using the Registry Editor, you can opt-in for third-party apps like Keytweak.

  2. Hover the mouse pointer over the keys on the on-screen keyboard of KeyTweak. It will show you the key mapping.
  3. For instance, I hovered the pointer over 31 and clicked it. It shows Key selected: 31 is currently mapped to “A”.
  4. Click Disable Key.
  5. Then click Apply button.
  6. Click Yes in the popup to restart your computer. This application will do the same in the registry settings we did in the second method to disable the key.
