Windows ‘Xbox UI’ leaked for all handhelds ahead of ROG Ally launch

Here is a 186-word summary of the news article: Microsoft is set to expand its new Xbox-style user interface to Windows-based handheld devices, with the upcoming Asus ROG Ally being the first to officially feature the gaming-focused interface. However, a leaked version of the interface has now been discovered, allowing users to try it on existing Windows 11 handhelds through some registry tweaks. The new interface is designed to address the issues Windows 11 faces on small, portable devices, providing a more controller-friendly experience. While Microsoft had planned to roll out the interface in early 2026, the leaked version has allowed eager users to get an early glimpse. Early tests of the unofficial implementation have shown modest performance improvements, such as a 5% boost in frame rates for Red Dead Redemption 2 and reduced memory usage in Celeste. These gains are expected to grow as Microsoft and its hardware partners continue to refine the interface. The leaked interface represents an exciting development for Windows-based gaming handhelds, offering the potential to enhance the user experience and performance across a range of devices.
