You can control the movement of your mouse cursor with the numeric keypad after enabling the Mouse keys feature in Windows 11/10. If your keyboard is controlling your mouse, check if you have enabled this feature or not. If the Mouse keys are already disabled, the cause of the problem lies somewhere else. If you have installed any mouse software, it might be controlling your mouse. To check this, kill that program via the Task Manager if it is running in the background and check if the issue persists.
