Microsoft is rolling out a new aggregated store system for Xbox Insiders participating in the Windows 11 PC Gaming Preview, featuring an updated Xbox PC app that compiles offerings from various PC storefronts. The app will automatically detect games installed from other platforms, currently including Battle.net, and add them to the library section. Users can disable this feature in the settings. The integration aims to improve navigation through different PC store apps using a controller, especially with the upcoming launch of the Xbox Ally. Additional Windows functionalities for controller navigation are also expected.
