It seems you are experiencing an issue with the 'M' key on your keyboard not functioning properly, even after trying a new keyboard. Here are a few troubleshooting steps you can consider:
- Check for Debris: Sometimes, debris under the keys can cause them to malfunction. Use compressed air to blow under the affected keys and clean them with a slightly damp microfiber cloth.
- Test in Safe Mode: Boot your computer into Safe Mode to see if the issue persists. If the key works in Safe Mode, a third-party application might be interfering with the keyboard functionality.
- Keyboard Troubleshooter: Run the keyboard troubleshooter in Windows 11 to identify any issues automatically.
- Driver Update: Ensure that your keyboard drivers are up to date. You can check for updates in the Device Manager.
- External Keyboard: If you haven't already, try using an external keyboard to see if the issue is specific to your current keyboard setup.
If none of these steps resolve the issue, it may be worth checking if there are any specific settings or software that could be affecting keyboard input.
