Other Notes
Microsoft is not planning to release SDKs for the 27xxx series builds for the time being.
Canary Channel builds represent the earliest platform changes and may not be tied to a specific Windows release; features can be changed, removed, or never released.
Some features in Canary may appear in Dev and Beta channels before Canary.
Here’s a summary of what’s new and notable in Windows 11 Insider Preview Build 27913 (Canary Channel), based on available sources and community analysis:
Key Features & Enhancements
No SDK Release (For Now):
Microsoft is pausing SDK releases for the 27xxx build series. For developers, this means there’s currently no new SDK to leverage features unique to these builds. This pause is likely to stabilize system components and allow internal API refinement before opening up to broader third-party development. Expect SDK releases to continue once Microsoft feels the series is ready for external development.
General Improvements:
Multiple background tweaks aiming at enhanced stability and reliability for preview users.
Improvements likely include minor performance optimizations, UI coherence, and more robust system processes. These are typical for early Canary builds and translate to a more stable future release.
Audio & Color Management:
Fixes for audio-related crashes (notably with WDMAud and MIDI enhancements), so users should see fewer unexpected crashes in creative or multimedia workflows.
More accurate listing and handling of color profiles in Settings, resulting in greater monitor color fidelity for designers or users with specialized visual needs.
Privacy Updates:
The Location History feature has been removed; Cortana and other apps will no longer have access to local device location history, reflecting Microsoft’s ongoing efforts to strengthen privacy controls.
Known Issues
Windows Hello PIN/Biometrics on Copilot+ PCs:
If you recently joined the Canary Channel from a different Insider channel or a retail build on a Copilot+ PC, you may lose your Windows Hello PIN and biometrics. An error (“Something went wrong, and your PIN isn’t available” with code 0xd0000225) appears. Workaround: Set up your PIN again from scratch.
d3d9.dll Crashes:
Some users continue to experience crashes with applications that rely on d3d9.dll. Microsoft is aware and working on a fix.
Canary-specific warnings:
As always, Canary builds may ship features or changes that are later pulled, altered, or never released. Clean install is required to leave Canary Channel.
Insider Experience & Feedback
This build continues Microsoft’s feedback-driven development approach—feedback from Insiders (via Feedback Hub and forums) is critical for identifying bugs, shaping features, and highlighting usability concerns.
Canary Channel users play a key role in providing rapid, early feedback on features and regressions.
Summary
No new SDK for build 27913—developers need to wait for future announcements.
Improved stability, audio, and color management.
Removed location history for better privacy.
Known issues mostly affect Copilot+ hardware and some power users.
Practical effects for most Insiders: a steadier, privacy-minded, developer-focused preview period.
