Whether you are a student, professional, developer or creator, a flawless typing experience is essential for anyone to get things done. When you throw words, you might notice that your keyboard acts weird and types multiple / double letters on Windows 10. If you are one of those affected, read the article to resolve the issue.

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