I'm running Windows 10, and for a few weeks now, it has been acting as if the CTRL key is jammed. I replaced my keyboard with multiple others, and the problem persisted. I read a few forums, and one suggested to press both CTRL keys at the same time, which only worked once. Then, another said to open the virtual keyboard. This showed clearly that the keys were indeed held down, but I couldn't deactivate them from there, so it really didn't help. Are there any fixes to this?
