Microsoftは7月24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 26257」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 26257の新機能
Build 26257では、ファイルエクスプローラーのタブの右クリックに「タブの複製」メニューが追加されています。また「設定 > Bluetoothとデバイス > マウス」にマウスポインタの精度向上(Enhanced Pointer Precision)をオフにすることができるスイッチが追加されています。
リリースノートは以下の通りです。
Changes and Improvements
[File Explorer]
- We’re rolling out the ability to duplicate a tab by right-clicking on a tab in File Explorer.
[Input]
- [ADDED] We have updated Settings > Bluetooth & Device > Mouse to now include the option to turn off enhanced mouse pointer precision for those that would prefer to not use it and have added a new option for changing mouse scrolling direction.
[Networking]
- If you use the netsh wlan show networks command, you should be able to read SSIDs that are UTF-8 encoded. This means that Wi-Fi SSIDs with Unicode characters (like emojis) should be properly displayed in netsh output. This change is beginning to roll out so not all Insiders in the Canary Channel will see it right away.
[For Developers]
- Updated the logic for the “End Task” option in the taskbar so that it no longer shows a Not Responding dialog to give confirmation before ending the task.
[Other]
- Updated System Info (msinfo32) to now follow your text size preference under Settings > Accessibility > Text Size.
Fixes
[General]
- Fixed an underlying issue causing some Insiders to see bugchecks in recent builds citing KERNEL_SECURITY_CHECK_FAILURE.
[File Explorer]
- Did some work to help address an issue where the address bar dropdown might appear unexpectedly while you were using File Explorer.
[Settings]
- Fixed an underlying issue leading to some of the pop-up windows in Settings unexpectedly appearing left aligned, for example, the window for selecting a custom color for Dynamic Lighting.
Known issues
[General]
- [IMPORTANT NOTE] We are investigating reports that some Windows Insiders in the Canary and Dev Channels are stuck on Build 26040 or Build 23620. The investigation is ongoing, however if you are impacted by this and really want to get onto the latest build in the Canary or Dev Channel today – you can download the latest ISO here and do a clean install and opt your device back into flighting in the Canary or Dev Channels.
[Windows Sandbox]
- [NEW] Windows Sandbox will fail to launch with error 0x80370106.
[Input]
- [NEW] We are working on the fix for an issue causing the emoji panel to close when trying to switch to the kaomoji and symbols sections, or after selecting an emoji.
[Task Manager]
- [ADDED] We’re investigating an issue causing graphs on the Performance page in Task Manager to not show the correct colors when using dark mode again.
