If your Windows OS system is not allowing you to type the same letter twice or double letter, it can be due to a configuration error in the Ease of Access settings. Many users took to the Microsoft Community Forums to explain the keyboard won’t allow typing double letters problem.

My keyboard won’t let me type the same letter twice. It’s as if the key “sticks” until I hit a different key. For instance, to type “letter”, I had to hit the Delete button between the two t’s. This also applies to arrow keys, backspace, etc.
The reason I think the keys are “sticking” is that when I try to play games, if I hit a key once it will act as if that key is being held down

Follow the steps given below to fix this problem on your Windows computer.
