I bet some of you have accidentily pushed the Windows key in the middle of a game. It's extremely frustrating. Moonlitenite wrote a guide where he explained how to eliminate the problem.
Yesterday I got a private message from Moonlitenite where he told me about a guide he published on WGTour.com. He wrote a few steps explaining how to get rid of the problems the Windows key creates for you in intense Starcraft games, for example.
I have a lot of friends who simply removes the key from the keyboard, but you don't have to do that. With a useful little program Moonlitenite is writing about you can disable and re-enable it just as you want. If you are about to play a game, disable it to eliminate the risk. When you are done you might want it back - easily fixed. Just run the program and you are done.
Read the WGTour dossier for more information. There is also a download link in it.
