I searched around on how to disable windows key like 10 years ago, and all I found was some .reg files that only work after you reboot your computer. I actually use my windows key about 100 times a day, just not at all while playing games. I never found any program that would handle it for me, so I quickly wrote some up. It should be possible to remap your windows key so it does something useful, like bdrop rines. These just disable. To re-enable, just close the program.
