7 Best Ways to Fix a Keyboard That Types Multiple Letters in Windows 10

1. Restart your PC

When going through any troubleshooting process, restarting your PC should be the first solution. Doing this might be enough to fix the problem as it clear any data slowing down your device and stops any tasks that are taking too much RAM.

Also, a reboot might fix some of the hardware and peripheral devices. If your computer just downloaded an update, you should restart it to ensure smooth functioning.

2. Check Your Keyboard for Dust

If your keyboard is a bit old, it might’ve collected enough dust or debris to stop it from working properly, especially if you prefer using mechanical keyboards. If you think this is the cause of your problems, you need to give your keyboard a good clean. Unfortunately, this goes further than turning your keyboard upside-down and shaking all the dust out.

For a mechanical keyboard, you can use a key puller to remove the keys and thoroughly clean them or use a small air blower. If your keyboard is part of a laptop, it may be a sign that you need to clean out the insides too.

Also, an improper connection could be the cause of your problem. If you are using a USB keyboard, disconnect and reconnect it or use a different USB port.

3. Run the Windows 10 Keyboard Troubleshooter

You can use Windows 10 built-in troubleshooters to fix some of the hardware issues. Follow these steps to run the keyboard troubleshooter:

1. Right-click Start > Settings (or press Win + I).
2. Head to Update & Security > Troubleshoot > Additional troubleshooters.
3. From the Find and fix other problems section, select Keyboard > Run the troubleshooter.
4. Follow the displayed instructions.

4. Run the Windows Security Tool

You can use Windows Security to scan your laptop or PC for malicious or corrupted files that could hinder the keyboard’s functionality. Here is how you can do it:

1. Open Settings, then head to Update & Security.
2. From the left pane, select Windows Security > Open Windows Security > Virus and threat protection.
3. Click the Quick scan button. Windows 10 will remove any detected harmful files.
4. Once the scan is complete, test your keyboard.

5. Update the Keyboard’s Driver

Your keyboard driver might be outdated or corrupt which is why there are some communication issues between the keyboard and the PC. To fix it, you should update the driver:

1. Right-click Start > Device manager.
2. Extend the Keyboard menu.
3. Right-click the driver and select Update driver.

If this doesn’t find anything, locate your keyboard’s manufacturer and model number and search for drivers on the company’s official website. You can usually find both on a sticker on the keyboard itself. Failing that, look for packaging or find a receipt of the purchase for more information.

6. Check the Windows 10 Language Settings

Windows 10 detects the default input language on your device but sometimes doesn’t get it right. This can then lead to keyboard-related issues. Here is how you can make sure you and your system are speaking the same language:

1. Open Settings.
2. Head to Time & Language > Language Keyboard.
3. In the Override for default input method section, use the drop-down menu to select your preferred language.

Also, you should remove any extra language packs or keyboard languages that you don’t use. Open the Language menu using the above steps and scroll down to Preferred languages. There, click the language you don’t use or have installed by accident and select Remove.

7. Change the Keyboard Repeat Delay

In Windows 10, you can use keyboard settings to change its key repeat delay from short to long. Follow these steps to delay the time between repeated keystrokes:

1. In the Start menu search bar, search for control panel and select the Best match.
2. Go to the View by menu and select Large icons or Small icons.
3. Select Keyboard to access its properties.
4. Click Apply > OK to save the new settings.
