Microsoft has announced that the Xbox app is now available on all Arm-based Windows 11 PCs. The release of the app 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 running games 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 “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, meaning you can access a wider library of online multiplayer games than 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 has taken a big step forward with the launch of its own Arm-based hardware and the CoPilot+ PC program in 2024. Many CoPilot+ PCs use Qualcomm’s Snapdragon chips, the latest of which the company announced for September 2025. Microsoft’s handheld efforts up to this point have been focused on PCs running AMD chips, but expanded support for Arm and Qualcomm’s own teases certainly seem to be the case. Arm-based Windows 11 handhelds may be announced soon.
