Xbox Handheld Full-Screen Mode Unlocked Early on Windows 11

The community workaround uses a Release Preview build with low‑level tweaks that can leave systems unstable.

Overview

  • Enthusiasts have enabled Microsoft’s new full-screen handheld experience on Windows 11 25H2, letting devices boot straight into the Xbox app.
  • The unofficial method works on multiple handheld PCs, including Asus ROG Ally models and MSI’s Claw, according to hands-on testing and community reports.
  • The mode suppresses the Windows Explorer shell and background processes, freeing roughly 2GB of memory for games and presenting a handheld-friendly task view.
  • The process requires joining the Windows Insider Release Preview, editing the registry and Windows Feature Store (Velocity), and carries risks that may require a rollback or reinstall.
  • Guides circulating on Reddit detail the steps, while Microsoft cautions desktop use is best with touch or a mouse; the partner-built ROG Xbox Ally and Ally X are slated to launch on October 16.
