Earlier this year, Microsoft and Asus announced the ROG Xbox Ally, an update to the first-gen ROG Ally, now adorned with Xbox branding. Along with the new name came new specs, but more importantly, the Xbox partnership wasn’t just a token collaboration — rather, a deeply integrated experience finally meant to "fix" Windows on handheld devices. Hence, the ROG Xbox Ally would ship with a new full-screen Xbox app that it would boot into by default, superseding Windows 11 entirely. This was exclusive to the ROG Xbox Ally and was supposed to come to other handhelds later; however, it seems the opposite has happened.
The Verge's Tom Warren reports that the full-screen Xbox experience meant for ROG Xbox Ally devices has leaked early, and can now be installed on any handheld running Windows. The actual ROG Xbox Ally is set to launch next month, which means that everyone else will get to enjoy Microsoft's new handheld gaming mode before the very device that was set to debut it. There's a full guide on Reddit that breaks down how to install it, and it's relatively easy to follow as long as you know your way around Windows. If you have a regular Ally, Lenovo's Legion Go, or the myriad of PC handhelds out there, you should be eligible.
