Alternatively, visit the manufacturer's website to download the latest driver manually.

4. Run the Windows Troubleshooter

Windows includes built-in troubleshooters that can identify and fix common issues.

  • Open Settings > Update & Security > Troubleshoot.
  • Select Additional troubleshooters.
  • Choose Keyboard and click Run the troubleshooter.
