This is how Microsoft is combining Windows and Xbox for handheld PCs
Microsoft introduced a new Xbox-focused full-screen experience that launches instead of the standard Windows desktop on ROG Xbox Ally devices, optimized specifically for gaming handhelds.. The handheld mode reduces background Windows processes, freeing up about 2GB of memory and cutting idle power draw by two-thirds, improving both speed and battery life.. The updated Xbox app now aggregates games from Steam, Epic, Xbox, and more, while the revamped Game Bar allows quick access to device settings, a new task switcher, and Microsoft's Gaming Copilot.. Players can navigate the entire interface using a controller, including the lockscreen and multitasking, with options like PIN login via controller.. The Xbox full-screen experience will first roll out to ROG Xbox Ally and Ally X, and will later expand to other Windows handhelds starting in 2026, marking a broader push to rival SteamOS in handheld gaming..
