7 best ways to fix multiple letter keystrokes in Windows 10

Whether you’re a student, professional, developer, or creator, a flawless typing experience is a must for anyone to get things done. As you fire words, you may notice that your keyboard is acting weird, typing multiple / double letters in Windows 10. If you are one of those affected, read the post to resolve the issue.

There are several factors that affect keyboard functionality in Windows 10. Let’s discuss them.

1. Clean the keyboard

This works for those who live in dusty environments. Over time, your keyboard may have collected small particles of dust under the keys.

If you’re a keyboard nerd and use a mechanical keyboard, you can actually use the key puller, remove each key, and then clean the keyboard.

For Windows 10 users on a laptop or regular keyboard, you can use a blower or compressed air to remove the dust from inside a keyboard.

When cleaning a keyboard, be sure to rotate the keyboard 75 degrees to make sure none of the twilight particles stay inside.

2. Scan your PC with Windows Security

Gone are the days when we relied on third-party antivirus software on Windows to remove malicious files. Some malicious or damaged files on your Windows computer can interfere with keyboard functionality.

Follow the steps below to scan your PC with Windows security software.

Step 1: Open the Settings app on your Windows device (use the Windows + I keys).

Step 2: Go to Update & Security> Windows Security.

Open the Windows security menu

Step 3: Open Windows Security from the side menu.

Step 4: Navigate to Virus & threat protection and do a quick scan on the PC.

Remove malicious files if there are any. Try using the keyboard as intended and see if Windows Security fixed the problem.

3. Restart the PC

You should restart your PC using the above methods. Open the start menu and restart the PC. Restarting the system can resolve minor inconveniences with the software.

4. Update the keyboard drivers

Outdated keyboard drivers on your Windows computer can affect keyboard performance, and at times the keyboard may type multiple letters in Windows 10.

You need to update the keyboard drivers to the latest version available. That’s how it’s done.

Step 1: Press the Windows key in the system tray.

Step 2: Look for Device Manager.

Open device manager

Step 3: You will find all installed hardware / network devices with a list of drivers.

Step 4: Navigate to Keyboard and select your keyboard.

Step 5: Right click on it and select the Update Driver option.

The operating system scans and installs the latest keyboard drivers from the Internet.

5. Adjust the keyboard repeat delay

Windows provides a native way to customize some of the keyboard settings. You can change the key repeat delay from short to long and fix multiple letter typing on the keyboard on Windows 10.

Go through the following steps.

Step 1: Press the Windows key on the system tray and look for Keyboard.

Open keyboard properties

Step 2: Open the keyboard properties.

Step 3: In the Character Repeat menu you will find the Repeat Delay option.

Windows provides a native troubleshooter for resolving problems with software features and hardware devices. You can run the keyboard troubleshooter and see if that solves the problem.

Step 2: Go to the Update & Security> Troubleshooting menu.

By default, Windows will automatically detect the default input language on the device. It is always a good idea to check the keyboard language settings. That’s how it’s done.

Step 1: Open the Settings app on Windows 10.

Open the keyboard language menu

Step 2: Go to Time & Language> Language menu.

Change keyboard language

Step 3: Select Keyboard and choose your preferred language from the menu below.

Corrected typing multiple letters on Windows 10

Follow the methods above, then try entering text on your computer. If the same problem still occurs, the problem may be with the keyboard. Try connecting it to another computer and see if the problem persists.

If the keyboard keeps typing multiple letters after pressing a single key, it can be annoying when notifying messages or when composing a document.
