How do I remove the limit on PC keyboard button presses?

Whenever I play a PC game with the directional keys, I can only press two buttons at a time. For instance if I am playing a shooter like R-Type, I cannot hold down the fire button while moving diagonally at the same time. The computer simply ignores the extra button press.

How do I remove this limit so I can shoot while moving diagonally? This limitation seems to apply for every game.

I am running Windows 7 if it makes any difference. I noticed the same problem back when I used Windows XP.


This is a hardware limitation of your keyboard. Unfortunately, the only solution is that you must purchase a better keyboard that does not have this limitation.

To be more specific:

In order to save money, keyboard manufacturers often put many keys on the same “circuit” of sorts within the wiring of the keyboard. This prevents multiple keys in the same region of the keyboard from being pressed simultaneously. Sometimes it even prevents more than 2 keys at all from across the whole keyboard being pressed at once. Often the shift, ctrl, and alt keys are not within this limitation, so you can hold shift and press 2 other keys at once and it will still work fine.

Even high-end gaming keyboards often have a similar hardware limitation, although the cap is much higher so that it is unlikely to be reached during the normal course of gaming.
