Microsoft is testing a new aggregated game library within the Xbox PC app for Windows 11 PCs and handheld devices, which allows Xbox Insiders to view their Steam and Battle.net games directly in the app. This feature will automatically populate the ‘My Library’ section when games from supported storefronts are installed. It aims to streamline access to game libraries, particularly for Windows-based handhelds, and is inspired by the success of the Steam Deck. The feature is currently available for testing and is expected to launch alongside Microsoft's gaming handhelds later this year, with plans for broader rollout to other Windows-based handheld devices.
