Windows 11 is undergoing a significant transformation for users with Arm processors, particularly with the introduction of build 27744 in the Canary channel. This update brings a noteworthy enhancement to the Prism emulator, which now supports a broader array of x86-based applications on Arm devices, effectively bridging the gap that previously limited the functionality of these systems.
The Prism emulator gets an upgrade on Windows 11
Originally unveiled with Windows 11 version 24H2, the Prism emulator has been a cornerstone in the evolution of Windows on Arm PCs. Despite its initial promise, some applications remained incompatible, hindering the full potential of Arm devices as replacements for traditional PCs. The latest build addresses this by incorporating support for additional CPU extensions, including AVX, AVX2, BMI, FMA, and F16C. While not essential for running Windows or most applications, these extensions have become standard expectations in various scenarios.
Microsoft has already rolled out a limited preview of this enhanced version of the Prism emulator to the public. Notably, Adobe Premiere Pro 2025 is now operational on Arm, thanks to this expanded support, with the new build making these additional extensions accessible to all compatible applications. However, it is important to note that these new features are currently limited to 64-bit x86 applications, leaving some 32-bit apps and those relying on 32-bit helpers unable to take advantage of the improvements. Microsoft hints that future updates may address this limitation.
Some smaller enhancements in tow
In addition to the major upgrade to the Prism emulator, this build of Windows 11 introduces several smaller enhancements. A new gamepad keyboard has been added, designed for use with gaming handhelds or controllers when a physical keyboard is impractical. This feature, while not entirely new, has been made available across other Insider channels.
Moreover, Microsoft has reinstated the option to detach a virtual hard disk from the Settings app and implemented minor improvements to Task Manager. A comprehensive list of fixes accompanies these updates, addressing various issues such as:
- Resolving black screen issues for Insiders with older NVIDIA GPUs.
- Fixing problems with the Emoji Panel and Clipboard History not opening in certain contexts.
- Enhancements to Windows Sandbox performance.
- Addressing dynamic refresh rate issues on first boot.
- Correcting various bugs that affected remote desktop connections and application crashes.
For those enrolled in the Canary channel of the Insider program, the latest build can be accessed by checking for updates on their PCs. However, broader rollout to all users will take time, as the Canary channel primarily tests platform changes, including the pivotal Prism emulator enhancements.
