Insider Windows 11 Insider Canary build 27744.1000 - Nov. 6

UPDATE 11/13:



Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27744 to the Canary Channel.

We are also not planning to release SDKs for 27xxx series builds for the time being.

What’s new with Build 27744​

New Processor Feature Support in Prism​

In today’s Canary Channel Insider Preview build, we’re previewing a major feature update to Prism, our emulator for Windows on Arm, that will make it possible for more 64-bit x86 (x64) applications to run under emulation by adding support for more CPU features under emulation.

This new support in Prism is already in limited use today in the retail version of Windows 11, version 24H2, where it enables the ability to run Adobe Premiere Pro 25 on Arm. Starting with Build 27744, the support is being opened to any x64 application under emulation. You may find some games or creative apps that were blocked due to CPU requirements before will be able to run using Prism on this build of Windows.

At a technical level, the virtual CPU used by x64 emulated applications through Prism will now have support for additional extensions to the x86 instruction set architecture. These extensions include AVX and AVX2, as well as BMI, FMA, F16C, and others, that are not required to run Windows but have become sufficiently commonplace that some apps expect them to be present. You can see some of the new features in the output of a tool like Coreinfo64.exe.


You can see some of the new features in the output of a tool like Coreinfo64.exe with newly exposed CPU features are highlighted above in green.

Note that in today’s preview, only x64 applications can use these new CPU features. If you have a 32-bit app or a 64-bit app that uses a 32-bit helper to detect CPU feature support, that app won’t detect the new features in Prism.

We welcome any feedback from Insiders who are interested in trying out apps and games using this early preview of Prism. Please submit any feedback on compatibility issues or performance regressions through the Feedback Hub (Win + F) under Apps and the specific app you’re seeing issues with (if you don’t see the app listed, use “All other apps”) to help us to ensure that this updated Prism provides a great experience.

Thanks for helping us improve emulation on Windows. We’re excited to see customers able to run more apps and games that they care about on Windows on Arm!

Reminders for Windows Insiders in the Canary Channel​

• The builds we release to the Canary Channel represent the latest platform changes early in the development cycle and should not be seen as matched to any specific release of Windowsand features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
• Many features in the Canary Channel are rolled out using Control Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
• Some features may show up in the Dev and Beta Channels first before showing up in the Canary Channel.
• Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
• To get off the Canary Channel, a clean install of Windows 11 will be required. As a reminder – Insiders can’t switch to a channel that is receiving builds with lower build numbers without doing a clean installation of Windows 11 due to technical setup requirements.
• The desktop watermark shown at the lower right corner of the desktop is normal for these pre-release builds.
• Check out Flight Hub for a complete look at what build is in which Insider channel.

Thanks,
Amanda & Brandon
