Microsoftは10月6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 27959」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 27959の新機能Build 27959で導入された注目の新機能は「ハードウェアインジケーターの位置変更」機能です。これまで画面下部に固定されていた「音量」「明るさ」「機内モード」などのインジケーターを、画面の「左上」や「中央上」に移動できるようになりました。▲インジケーターが「左」の場合。▲インジケーターが「中央」の場合。▲「設定 > システム > 通知 > オンスクリーンポップアップの位置」から変更することができます。また、文章作成時に便利な「Enダッシュ(–)」と「Emダッシュ(—)」を簡単に入力できるショートカットが追加されました：Win + -：EnダッシュWin + Shift + -：Emダッシュ※「拡大鏡」使用時は従来通りズームアウト機能が優先されます。Windows共有機能の強化が行われ、共有ウィンドウにお気に入りのアプリを「ピン留め」できるようになり、頻繁に使う共有先へのアクセスがよりスムーズになりました。その他、「アプリが開けない」時に表示されるダイアログもWindows 11のビジュアルスタイルに統一され、より洗練された印象になっています。リリースノートは以下の通りです。What’s new in Build 27959 Changes and ImprovementsNew setting to move hardware indicators on your screenWe’re excited to introduce a highly requested setting, the option to move the hardware indicators for brightness, volume, airplane mode, and virtual desktops to different positions on your screen.
