Microsoftは7月25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 27909」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 27909の新機能
Build 27909では、管理者保護が有効な場合にXboxアプリが起動しない問題の修正や、「設定 > システム > 電源とバッテリー」の上部にバッテリー残量のパーセンテージが表示されない問題の修正、Arm64 PCにおいて、リモート デスクトップ使用時に極端なグラフィックの歪みや描画の問題が発生するバグの修正が行われています。
リリースノートは以下の通りです。
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.
Fixes
[Administrator Protection]
- Fixed an underlying issue where the Xbox app wouldn’t launch when administrator protection was enabled. This may have also impacted other apps too, showing error 0xC0000142 or 0xC0000045.
[Settings]
- Fixed an issue where the battery percentage was unexpectedly missing from the top of System > Power & Battery in the last few builds.
[Remote desktop]
- Fixed an issue causing extreme graphical distortion and rendering issues using remote desktop on Arm64 PCs in the last couple builds.
[Other]
- Fixed a high hitting pcasvc.dll crash in the previous build.
- Fixed an underlying issue where if you disconnected the device you were casting to from outside of Media Player, Media Player would still show an option to disconnect from the device.
- Fixed an issue which was causing Remote Credential Guard scenarios between the latest Windows 11 builds and Server 2022 (and below) to fail.
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”.
- There’s an issue starting with the latest builds causing a small number of Insiders to experience repeated bugchecks with KERNEL_SECURITY_CHECK_FAILURE after upgrading.This may occur when connecting to VPN.
- This Canary Channel flight comes with a delightful blast from the past and will play the Windows Vista boot sound instead of the Windows 11 boot sound. The fix should be coming in a future Canary Channel flight soon.
[Settings]
- We’re investigating an issue in this build which could cause Settings to crash when interacting with the options under Settings > System > Power & Battery.
- We’re investigating an issue where some of the apostrophes across text in Settings and settings-related dialogs are not displaying correctly and are showing random characters.
