All gamesAll works fine here. It must be something on your side then. Actually, I have the same problem. I've checked the option to disable the GUIDE button within Steam Big Picture, but when I launch a game, pressing the GUIDE button always takes me back to the Start Screen. I've als tried running xbstart with administrative rights which didn't help. The Guide button deactivation works only when a game is launched with a Steam big picture, when you run a game with it's own pinned shortcut It cannot be done at the moment unfortunately. I always Launch my games within Steam Big Picture but the GUIDE button still throws me back to the start Screen. Am I doing something wrong? Do you Need more info?
