7 Best Ways to Fix Keyboard Typing Multiple Letters in Windows 10

Whether you are a student, professional, developer, or creator, a flawless typing experience is a must-have for anyone to get things done. When firing up words, you may notice your keyboard acting up weirdly and typing multiple/double letters on Windows 10. If you are among those affected ones, read the post to troubleshoot the issue.

There are multiple factors affecting the keyboard function on Windows 10. Let’s discuss them.

1. Clean Keyboard

This one works for those living in dusty environments. Over time, your keyboard might have gathered small dust particles under the keys.

If you are a keyboard nerd and use a mechanical keyboard, you can actually use the key puller, remove every key, and then clean the keyboard.

For those using Windows 10 on a laptop or using a normal keyboard, you can use a blower or compressed air to clean the dust inside a keyboard.

While cleaning a keyboard, make sure to rotate the keyboard 75 degrees to make sure none of the dusk particles stay in.

2. Scan PC With Windows Security

Gone are the days when we used to rely on third-party antivirus software on Windows to remove harmful files. Some malicious or corrupted files on your Windows machine might interfere with the keyboard functions.

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