Disable Windows Keys: The simplest way to disable the Windows keys!

My previous keyboard had a "Game Mode" functionality that just disabled the Windows Key, and well, I just got a new one, and this does not have it. Why do I need this app? Well, there's nothing worse than while you are in the middle of something important, like a battle on an online FPS, you accidentally hit the Windows key and you get out of the game, and well, you lose. Some apps can solve this problem, but the ones that just focus only on this problem are not Windows 10 compatible, some others try to do many more things that I don't need, so I found this one that does just what I need and nothing more. It is also pretty nice that it is open-source, so you can see what is really going on, but just go and buy it for a dollar if you find it useful.
