MT-

I had the same issue when I got this keyboard. The reason this has occurred is the keyboard is in game mode. Apparently, when in game mode, the windows key is disabled. The fix is easy, just put the keyboard back into normal mode. This can be accomplished by holding down the (Fn) button, then pressing the (PrtScr/SysRq) button, just to the right of the F12 button. Now your windows key should be active. Hope this helps.
