If your computer is executing commands that you don’t need, such as punctuating words in the middle of sentences, the problem may be related to sticky keys — a system in which instead of holding down a key to execute a command, you press it, and it remains pressed until you press another key.
The instructions in this article apply to Windows 10, Windows 8, and Windows 7.
What are sticky keys?
Each keyboard uses keys- modifiers, keys that change the function of a letter key. The most commonly used is Shift, which changes lowercase letters to uppercase.
Depending on the programs you use on your computer, you can also use the Ctrl, Alt keys, the Windows key on Windows devices, and the Command key on Mac.

Sticky keys help people with disabilities or suffer from repetitive stress injuries. Instead of holding down a key, you can press it and it will stay «down» until you press the button. On Windows 7, 8, or 10, try this feature by pressing the Shift key five times. A window will appear asking if you want to enable sticky keys. After that, try typing something and you’ll see it in action.
Sticky keys can be very useful if you don’t like holding down a key for a long time. If you’re not a touch typist in particular, or if you’re learning how to use software that makes heavy use of modifier keys, this can be helpful while you keep track of which key you want to press. Otherwise, they are probably not worth leaving.

The easiest way to turn sticky keys on and off in Windows 10 is with the technique described above. If you press Shift five times with sticky keys enabled, it will turn off. You can also press any two keys at the same time and that will disable it.
If the above doesn’t work or you want to disable this shortcut in settings, follow these steps:
