Fix Left Ctrl Key Not Working on Windows 11

Having trouble with your left Ctrl key not working on Windows 11? Let’s troubleshoot the issue together.

Identifying Physical Issues

To identify physical issues causing the left Ctrl key to not work on Windows 11, start by checking for any visible damage or debris on the key itself. Next, inspect the keyboard connection to ensure it is securely plugged into the computer’s USB or PS/2 port. Additionally, try connecting a different keyboard to see if the issue persists, which can help determine if the problem lies with the keyboard or the computer.

If the issue is isolated to the keyboard: Consider cleaning the key or replacing the keyboard if necessary. If the problem persists with multiple keyboards, it may indicate a hardware issue with the computer itself.

If the problem is with the computer: Check the Device Manager for any driver issues related to the keyboard or human interface devices. Ensure all drivers are up to date by accessing the Device Manager through the Control Panel.

After selecting your keyboard, click on Properties. In the Properties window, go to the Driver tab and click on Update Driver. Follow the on-screen instructions to update the driver. Finally, restart your computer for the changes to take effect. This should help resolve the issue with the left Ctrl key not working on your Windows 11 system.
