Now, try to operate your keyboard/mouse as you would typically, and you will notice that your problem is gone. Start the Windows 11 / 10 Run Dialog via Windows-Logo+R keyboard shortcut and enter the command control.exe /name Microsoft.Mouse or main.cpl. The simplest way is, over the Command: control.exe /name Microsoft.Mouse. Blow air under the key(s) and press them both a few times, so if any sort of a tiny crud/solid object is stuck between the key and the contact point, they would either break off or move away. If you want to change the Mouse double click settings, please open the Mouse Properties in Windows 10. Once you remember that you have done one of the above mentioned thing(s) to your keyboard, feel silly, and let all your worries about your “hacked” computer go away, because this is just a small issue where the Alt key is pressed down. I want you to retrace your steps, and try to remember if you either cleaned your keyboard recently, or sat on it, or fell asleep on it, or hit it because you couldn’t get a kill and your teammates roasted you.
