Microsoftは12月4日(現地時間)、Windows 11のWindows Insider ProgramのCanaryチャンネル向けの最新ビルド「Windows 11 Insider Preview Build 27758」をリリースしました(Windows Blog)。
Canaryチャンネルで公開されるビルドは、将来の機能アップデートで追加される可能性のある、さまざまな新機能が先行して実装されています。プレビューチャンネルの中で最も不安定な可能性があり、提供されるドキュメントも限定的なものとなっています(例えば既知の不具合は掲載されないなど)。
Windows Insider Programの更新オプションでCanaryチャンネルを選択し、Windows 11のプレビュー版を使用しているユーザーは、Windows Updateを利用して最新版に更新することができます。
Build 27758の新機能
Build 27758では、ファイルエクスプローラーの検索ボックスがウィンドウの端からはみ出さないための調整や、タスクバーのアプリアイコンを右クリックするとexplorer.exeがクラッシュすることがあった問題の修正、一部のアプリケーションでテキストフィールドにマウスカーソルを置くと、マウスカーソルが見えなくなる問題の修正などが行われています。
リリースノートは以下の通りです。
Fixes
[File Explorer]
- Did some work so the search box in File Explorer shouldn’t draw off the end of the window anymore.
[Taskbar]
- Fixed an issue where right clicking on app icons in the taskbar might crash explorer.exe in the previous flight.
[Input]
- Fixed an issue for some people where the mouse cursor would become invisible when hovering over text fields in certain apps.
[Desktop]
- Fixed an issue where your desktop background might not show correctly sometimes with multiple monitors (showing big black areas).
[Task Manager]
- We are beginning to roll out a fix for the issue where if you resized Task Manager to be larger while settings was open, the Mica background wouldn’t align with the new window size.
[Narrator]
- Fixed an issue in the previous flight which caused Narrator to crash on launch if you used one of the natural voices (like Jenny).
[Audio]
- Fixed an underlying issue which could lead to USB audio devices going to sleep after 1 minute of idle time, and not waking up until the PC was rebooted.
- Fixed an underlying issue which could lead you to unexpectedly hear a mute or unmute noise in certain headsets.
[Settings]
- Fixed an issue which could cause Settings to crash when selecting your default audio device.
[Other]
- Fixed an issue which could cause an unexpected black line along the top border of a window.
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”.
- We’re investigating reports that some Insiders are still experiencing rollbacks (with error code 0xc190010) when attempting to install the latest Canary builds.
- We’re working on the fix for an underlying issue causing accent colored window borders to not be not displayed when enabled, shadows around windows not displaying when enabled, and window launching (and other) animations to show even though the setting to show animations is turned off.
- [NEW] We’re working on the fix for an issue causing some Insiders to see a bugcheck with error PAGE_FAULT_IN_NONPAGED_AREA starting with the previous flight.
