Microsoftは8月14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 27924」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 27924の新機能
Build 27924では、Copilot+ PCで「Recall」「Click to Do」「改良版Windows検索」「リアルタイム翻訳付きライブキャプション」「設定内エージェン」などAI機能の段階的ロールアウトが開始しています。
また従来の「開発者向け設定（For Developers）」ページを再設計した「高度な設定」ページが新設されました。長いパスの有効化（MAX_PATH制限の解除）、仮想ワークスペース（Hyper-V、Windows SandboxなどのON/OFF）、ファイルエクスプローラーのGit連携（ブランチ、差分、コミット情報の表示）など各種機能のオンオフを切り替えることができます。
リリースノートは以下の通りです。
Copilot+ PC experiences
We are beginning to enable many of the Copilot+ PC experiences* for Windows Insiders in the Canary Channel on Copilot+ PCs such as:
- Recall (Preview)
- Click to Do (Preview)
- Improved Windows Search
- Live captions with real-time translation
- Agent in Settings
Note that some features are gradually rolling out such as Improved Windows Search and agent in Settings. And we’re still working to enable some features like image descriptions in Narrator – so if you don’t see something right away on your Copilot+ PC after updating to this build, that’s expected. We’re working hard to get everything enabled across the board over for the Canary Channel.
As is normal for the Canary Channel, the quality of these features will not match the quality of the same features in the Dev or Beta Channels. Expect some of these features to not work quite right. We will try to document known issues for the most impactful issues for these features and one such issue regarding Click to Do is documented in the known issues below. As always, please file feedback on any issues you see when using these Copilot+ experiences via Feedback Hub.
Advanced Settings
Advanced settings are now available via Settings > System > Advanced with some new features. The Advanced page is a redesign of the For Developers page, intending to make its settings easier to find for a broader audience. With the redesign of this page, we’ve added additional settings: Enable long paths, Virtual workspaces, and File Explorer + version control.
Enable long paths allows you to remove MAX_PATH limitations from common Win32 file and directory functions. Virtual workspaces allow you to enable/disable virtual environments such as Hyper-V, Windows Sandbox, and more. File Explorer + version control provides the ability to display Git information directly inside File Explorer. Simply select your repository folder and File Explorer will display information such as your branch, diff count, last commit message, and more.
FEEDBACK: Please file feedback on GitHub at microsoft/WindowsAdvancedSettings.
Changes and Improvements
[Input]
- Adjusted the pointer indicator to be a little more transparent, so it’s easier to see what’s under the crosshairs when it’s enabled.
- For the time being we have changed the keyboard shortcut for the new pointer indicator from CTRL + WIN + X to CTRL + WIN + ALT + X, to help reduce accidental invocations.
[Windows MIDI Services]
- The inbox preview MIDI Service and API has a feedback-driven breaking change to optionally allow for waiting for messages to be completely sent before returning from function calls. Any apps written against previous versions of the Windows MIDI Services MIDI 2.0 SDK will need to update to the latest preview available at https://aka.ms/midireleases and be recompiled to continue working properly. For more discussion and feedback, please join our discord server at https://aka.ms/mididiscord.
Fixes
[General]
- Fixed an issue where the progress wheel might show as a rectangle glyph instead of rendering correctly when upgrading to the latest builds.
[Widgets]
- Fixed an issue causing widgets to disappear or not work for some Insiders after the previous flight.
[Remote desktop]
- Fixed an issue in the latest flights where remote desktop only used your primary monitor even if it was configured to use multiple monitors.
[Other]
- Fixed an underlying webauth.dll crash in the previous flight which may have impacted the ability to use passkeys.
Known issues
[General]

You should be able to re-create your PIN by clicking “Set up my PIN”.
