With this update, it is now this list of shortcuts that appears when you press the central button of the Xbox controller, when you are not in game. The traditional menu, which groups together the different functions of the Game Bar (resource monitor, Xbox contacts, screenshots…) will continue to appear once the game is launched.
Practical, this function therefore offers very fast access to your games as soon as you access the Windows desktop, without using the mouse or the keyboard.

To benefit from this new function, still at the test stage, you must obviously be a member insider and download the most recent version of Windows 11, which has been available for download for a few hours. But that’s not all: you must then download the Xbox Insider Hub from the Microsoft Store, activate Windows Gaming Preview in the menu Previews, then make sure, still in the Microsoft Store, that you have the latest version of the Xbox Game Bar app.
