Announcing Windows 11 Insider Preview Build 27818 (Canary Channel)

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27818 to the Canary Channel.

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

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.

[Windows Security]

  • We are beginning to roll out 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]

  • Suggested actions that appear when you copy a phone number or future date in Windows 11 are now deprecated. We are disabling this feature.

Fixes

[General]

  • Fixed a d3d9.dll crash which was causing multiple apps to fail to launch starting with Build 27802 for some Insiders.

[File Explorer]

  • Did some more work to improve the performance of extracting zipped files in File Explorer, particularly where you’re unzipping a large number of small files.
  • Fixed an issue where File Explorer Home might not load correctly and just show random floating text saying “Name”.

[Taskbar & System Tray]

  • Fixed an issue with the taskbar app window previews, where the corners of the flyout weren’t drawn with the correct radius in certain cases.
  • Fixed an issue where the underlines under app icons in the taskbar may get stuck showing even if the app had been closed.

[Input]

  • Fixed a high hitting ctmon.exe crash, which could impact the ability to type.

[Settings]

  • Fixed an underlying issue which could result in Settings failing to launch with “The instruction at 0x00007FFEDEBDC003 referenced memory at 0x0000000000000010. The memory could not be read”. If impacted, you might also see a similar error message with RuntimeBroker.exe.
  • Fixed an issue for Japanese users, where the name displayed at the top of Settings > Accounts showed First Name Last Name instead of Last Name First Name.

[Graphics]

  • Fixed an issue which could cause sluggish video when using multiple monitors after changing from Second Screen Only to Duplicate display mode in the latest Canary builds.
  • Made a couple of fixes to address issues which could cause Settings > System > Display > Graphics to crash.
  • “Fixed an underlying issue which could lead to certain games failing to launch after an upgrade, saying DirectX function CreateComputePipelineState failed with E_INVALIDARG or StorePipeline failed with E_UNEXPECTED.

[Admin Protection]

  • Fixed an issue which could cause Visual Studio Code to not be able to be installed when Admin Protection was enabled.

[Remote Desktop]

  • Fixed an issue which could lead to Remote Desktop freezing when connecting.

[Other]

  • Fixed an underlying issue which was causing certain apps to fail to open with an error saying “The application was unable to load a required virtual machine component”.

Known issues

[General]

  • [IMPORTANT NOTE FOR COPILOT+ PCs] If you are joining the Canary Channel on a new Copilot+ PC from the Dev Channel, Release Preview Channel or retail, you will lose Windows Hello pin and biometrics to sign into your PC with error 0xd0000225 and error message “Something went wrong, and your PIN isn’t available”. You should be able to re-create your PIN by clicking “Set up my PIN”.

[Taskbar]

  • [NEW] We’re working on the fix for an issue where the taskbar icons aren’t increasing in size as they should when using your PC in a tablet posture.

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 & Brandon
