Announcing Windows 11 Insider Preview Build 27954 (Canary Channel)

This post has been republished via RSS; it originally appeared at: Windows Blog.

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27954 to the Canary Channel.

What’s new in Build 27954

Changes and Improvements

[General]

  • This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.

[Networking]

  • Fixed an issue where you might not be able to connect to shared files and folders if you were using the Server Message Block (SMB) v1 protocol on NetBIOS over TCP/IP NetBIOS (NetBT) after the latest updates.

Known issues

[General]

  • We’re working on the fix for an issue causing some Insiders with Arm64 PCs to experience an increase in bugchecks (green screens) with error IRQL_NOT_LESS_OR_EQUAL in the latest Canary builds.

[For developers]

  • PIX on Windows is unable to play back GPU captures on this OS version. This will be addressed by a new PIX release, estimated to arrive by the end of September. In the meantime, if you are impacted, you can use the "Send Feedback" button in PIX or contact us on the DirectX Discord server and we can help provide private builds.

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 Windows and 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
