Announcing Windows 11 Insider Preview Build 27842 (Canary Channel)

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 27842 to the Canary Channel.

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

Changes and Improvements

[General]

  • The improved battery iconography in Windows 11 may disappear for Windows Insiders in the current flights. We’re beginning to re-roll this change out to Windows Insiders.

  • We’re previewing a new, more streamlined UI for unexpected restarts which better aligns with Windows 11 design principles and supports our goal of getting users back into productivity as fast as possible. We’ve simplified your experience while preserving the technical information on the screen. As a reminder, for Windows Insiders this appears as a “green screen”. This is currently rolling out to Windows Insiders on Windows 11, version 24H2 and higher in the Beta, Dev, and Canary Channels.

[Windows Security]

  • We are beginning to roll out (again) a change in the Windows Security app where will show more details such as manufacturer and manufacturer version for Pluton TPM chips if your PC has one under Device security > Security processor details.

[Other]

  • Support for the Visual Studio Graphics Analyzer’s shader debugging feature is being removed. In this build, attempting to use it may crash Visual Studio or the analysis session. It is recommended that customers use alternative graphics debuggers such as PIXfor D3D12 or RenderDoc.

  • We’re removing the bypassnro.cmd script from the build to enhance security and user experience of Windows 11. This change ensures that all users exit setup with internet connectivity and a Microsoft Account.

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.
