Latest Windows 11 Insider Preview brings updated Prism emulator for Arm PCs

One of the main issues with Windows on Arm so far has been compatibility with x86-based apps and games. Microsoft’s new Windows 11 Insider Preview build 27744 features an updated Prism emulator for Arm PCs that brings support for additional CPU extensions including AVX, AVX2, BMI, FMA, and F16C. This means that apps like Adobe Premiere Pro 2025 and gaming titles like Starfield and Helldivers 2 will now work on Arm PCs.

In addition to the updated Prism emulator, the new Insider Preview build brings a new on-screen gamepad keyboard, which allows you to navigate and type in Windows 11. This feature would be a great addition to gaming handheld and touchscreen devices.

The rest of the changelog includes the ability to detach a hard disk from the Settings app, improvements to the Task Manager, and other minor bug fixes.
