Microsoft is set to introduce its new Xbox full-screen experience on upcoming Xbox Ally handheld devices next month, but Windows 11 users can already access this feature early through a series of tweaks.
The full-screen mode, part of the Windows 11 25H2 update, transforms handheld gaming PCs into a more streamlined gaming interface. Enthusiasts have shared methods to enable it via the Release Preview build of Windows 11, involving registry modifications and adjustments to the Windows Feature Store, known as Velocity. This approach works on devices like MSI’s Claw and Asus’ ROG Ally series, bypassing manufacturer-specific software for Microsoft’s native Xbox app.
Tom Warren of The Verge tested the setup on the original ROG Ally, where the device boots directly into the Xbox PC app, skipping the full Windows desktop and unnecessary background processes. This optimization frees up approximately 2GB of memory, enhancing performance for gaming by suppressing elements like the Explorer shell.
Once activated, users enter a dedicated Xbox environment that aggregates games from multiple platforms, including the Microsoft Store, Battle.net, Steam, and others. Navigation is facilitated by the Game Bar, while a redesigned task view caters specifically to handheld controls, making it more intuitive for portable play. Importantly, the mode retains flexibility: users can switch to the full Windows desktop or run Windows apps and games within the full-screen Xbox interface.
Microsoft has issued a cautionary note, advising that transitioning to the desktop mode works best with touch input, a mouse, or keyboard, as the experience mirrors standard Windows on other devices. While the process is described as relatively straightforward, it carries risks. Altering registry settings or Velocity could lead to system instability, potentially necessitating a rollback or full Windows reinstall.
For those interested, a detailed guide is available on Reddit, outlining all required settings. This early access highlights Microsoft’s push toward a unified, console-like experience on Windows handhelds, even as official support awaits the Xbox Ally launch in October 2025. The development underscores ongoing efforts to optimize PC gaming for portable devices, potentially influencing future handheld ecosystems.
