Microsoftは本日、Windows 11のプレビュービルド「Windows 11 Insider Preview Build 22621.1546 と22624.1546(KB5025310)」をWindows Insider ProgramのBetaチャンネル向けに公開しました(Windows Blog)。
ベータチャンネルは2つのグループに分けられており、それぞれのグループに別のビルドが提供されています。
- Build 22624.xxx: 新機能がロールアウトされる。
- Build 22621.xxx: 新機能がデフォルトでオフ。
これまでBuild 22623だったインサイダーは、有効化パッケージを経由して自動的にBuild 22624に移行されます。
新機能がデフォルトでオフになっているグループ(Build 22621.xxx)となったインサイダーも、アップデートを確認し、機能がロールアウトするアップデート(Build 22624.xxx)を選択しインストールすることが可能です。
Build 22624.1546の新機能
Build 22624.1546の新機能では、主に設定画面の改善が行われています。
設定画面の検索パフォーマンスが改善されたほか、PrintScreenキーを押すとデフォルトでSnipping Toolが開くようになる変更(「設定 > アクセシビリティ > キーボード」でオフにすることができる)、ALT+TABやスナップアシストでタブを表示する場合、「設定 > マルチタスク」で直近のタブを20個までとする制限の導入が行われています。
リリースノートは以下の通りです。
Changes and Improvements in Build 22624.1546
[General]
- In the previous flight, we documented that Content Adaptive Brightness Control (CABC) works on desktop PCs – however, it does not. We have updated that blog post. Content Adaptive Brightness Control (CABC) also needs to be enabled by the OEM (the manufacturer of the device). As a result, this feature is not available on all laptop or 2-in-1 devices.
[Settings]
- Improved the performance of search within Settings.
- Pressing the print screen key will now open Snipping Tool by default. This setting can be turned off via Settings > Accessibility > Keyboard. If you have previously modified this setting yourself, your preference will be preserved.
- A limit of 20 most recent tabs has been introduced under Settings > Multitasking to show tabs in ALT + TAB and Snap Assist.
Fixes in Build 22624.1546
[Input]
- Fixed an issue where text input features like touch keyboard, voice typing, and emoji panel might not launch.
- Fixed an issue where the buttons in the Pinyin IME’s settings flyout were hard to see when they had focus if a contrast theme was enabled.
[Task Manager]
- Fixed an issue where some of the details in the Performance page wouldn’t display properly until you resized the window or changed pages back and forth.
Known issues
[Search on the Taskbar]
- If you have the Bing button in the search box on the taskbar and you restart your computer, you may see the daily rotating search highlight for some time before getting the Bing button back.
[File Explorer]
Insiders who have access keys in File Explorer:
- [NEW] Shift + Right click on a file or folder is not opening “Show more options”.
[Live captions]
- On ARM64 devices, enhanced speech recognition support installed through the Language & Region settings page will require restarting live captions if you switch languages in the live captions Caption language menu.
- Certain languages shown on the Language & Region settings page will indicate speech recognition support (e.g., Korean) but don’t yet have support for live captions.
- When adding a language through the Language & Region settings page, language feature installation progress may become hidden, and you may not see install completion of “Enhanced speech recognition” (required by Live Captions). (You can use the language’s “Language options” to monitor progress.) If this happens, there may be an unexpected delay before the live caption setup experience detects this and lets you continue.
- Captioning performance may be degraded in non-English languages and missing out-of-language filtering in non-English (United States) languages which means that incorrect captions will be shown for speech not in the caption language.
