Microsoft has announced that the Xbox app is now available on all Arm-based Windows 11 PCs. The app’s release follows an update Microsoft made to its Prism emulator in December 2025, which translates x86 and x64 apps to Arm, and now includes support for AVX and AVX2. Both extensions play a role in making games run efficiently on Windows.
Windows on Arm users will be able to use the Xbox app to purchase, download and stream PC games, and Microsoft says that “more than 85 percent of the Game Pass catalog” now runs on Arm PCs. Unlike Valve’s SteamOS, Windows on Arm also supports anti-cheat software like Epic’s Easy Anti Cheat, which means you can access a wider library of online multiplayer games in comparison to what you can get on the Steam Deck.
Microsoft has been working on getting Windows running on Arm for years at this point, and the company made a major push with its own Arm-based hardware and the launch of the Copilot+ PC program in 2024. Many Copilot+ PCs use Qualcomm’s Snapdragon chips, the latest of which the company announced in September 2025. Up until this point Microsoft’s handheld efforts have been focused on PCs running AMD chips, but expanded support for Arm and Qualcomm’s own teases certainly makes it seem like an Arm-based Windows 11 handheld could be announced sooner rather than later.
