Microsoftは本日、Windows 11のプレビュービルド「Windows 11 Insider Preview Build 25188」を、Windows Insider ProgramのDevチャンネル向けにリリースしました(Windows Blog)。
本ビルドの注目点は以下の通りです。
- 新しいタッチキーボードの設定のテスト。Windowsターミナルがデフォルトのターミナルになった。
- Windows Insiderの全体的なエクスペリエンスを向上させるための優れた修正一式が含まれている。
- Microsoft Storeのアップデートをリリース。
- .NET Framework 3.5に依存するアプリが壊れる可能性のある新しい既知の問題が追加。.NET Framework 3.5を使用するアプリケーションを使用している場合、このビルドへのアップデートを控えて、フライトを一時停止することが推奨。
Dev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。特定のリリースとは直接結びつけられておらず、ビルドに含まれる新機能や改善点は、準備が整い次第、将来のWindowsリリースに反映される可能性があります。
Windows Insider Programの更新オプションでDev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 25188の新機能
Build 25188の新機能は以下の通りです。
タッチキーボード設定の更新
「キーボードが装着されていないときにタッチキーボードを表示する」タッチキーボードの設定(チェックボックス)をドロップダウンメニューで置き換えるテストを実施。「表示しない」「キーボード未装着時」「常に」が選択可能。
また、Windowsターミナルがデフォルトのターミナルとして使用されるようになっています。これは、コマンドラインプロンプトやPowerShellなどすべてのコマンドラインアプリケーションが自動的にWindowsターミナルで開かれる事を意味しています(Windowsターミナルv1.15以降が必要)。
その他の修正内容は以下の通りです。
[Taskbar]
Fixed an issue related to the taskbar overflow which was impacting explorer.exe reliability.
[Start]
Fixed an issue that was causing Start’s recommended to only show one column instead of two.
Made a fix for Narrator mistakenly reading out the search box in Start twice.
Fixed an issue where the access keys (underlined letters) in WIN + X had duplicate definitions when an update was pending reboot.
[File Explorer]
Fixed an issue causing a small percentage of Insiders to experience repeated explorer.exe crashes after attempting to access certain folders on their systems in the last couple Dev Channel builds.
Fixed a recent issue where if File Explorer was open when you switched between light and dark mode, you could end up with some unreadable text / UI showing the wrong color.
Fixed an issue that was causing explorer.exe to crash when opening folders with certain images.
The up arrow should no longer be misaligned in File Explorer.
Fixed an issue which could lead to not being able to unpin Desktop, Pictures, or Documents folders from Quick access.
Fixed an underlying explorer.exe crash which could happen when File Explorer launch was aborted, for example if you were attempting to access a network share from the Run dialog, were prompted for credentials, and then clicked cancel instead of entering them.
If the tab title is too long to display completely in the available space, hovering your mouse over it will now show a tooltip with the full name.
Fixed an issue which could lead to explorer.exe crashing when File Explorer was closed.
Fixed an issue causing the delete key to unexpectedly not work on files in File Explorer sometimes.
Removed the toolbar some people were unexpectedly seeing (with View / Edit / etc) after the introduction of tabs in File Explorer. As part of this, the “always show menus” option in Folder Options was also removed which didn’t do anything.
[Search]
Fixed an underlying crash which could lead to search not launching.
Searching for “detect displays” will now return Display Settings.
[Input]
Made a number of updates to emoji keywords based on feedback, including fixing that searching for apple didn’t return the red apple emoji in Korean or Polish (in the respective languages), searching for trash or garbage in English should now return the wastebasket emoji, searching for roger in English should now return the saluting face emoji, and searching for bug will now return the ladybug emoji. Please continue sharing feedback about emoji search results under Input & Language > Emoji Panel in the Feedback Hub!
[Settings]
Fixed an issue where in certain cases removing a printer from Settings wouldn’t work.
Fixed an issue where the DNS suffix search list entry wasn’t displaying correctly in Settings.
Fixed an issue where the buttons for changing current view in Settings > Apps > Installed apps might unexpectedly show arrows overlaid on top.
[Task Manager]
Updated the positioning of the View button tooltip position so it shouldn’t block the close button in the title bar anymore.
The arrow shown when sorting processes by CPU should no longer be black on black in certain cases when using dark mode.
Updated the selection highlight color when you select rows on the Details or Services page to be less bright and more aligned with the other colors used with the updated Task Manager design.
[Other]
Fixed an issue leading to missing / broken characters on the Bitlocker screen when using the Japanese display language.
Fixed an issue where the Advanced Settings of an application pool on a remote IIS server would display a blank screen.
Fixed an issue where Steps Recorder wouldn’t close when you pressed ALT + F4.

Some games that use Easy Anti-Cheat may crash or cause your PC to bugcheck.
We’re looking into reports that audio stopped working for some Insiders after upgrading to the last flight.
We’re investigating reports of a few different apps having started crashing in recent builds.
[NEW] Enabling .NET Framework 3.5 from the Windows Features dialog will not work in this build. If you had it enabled prior to upgrading, it may become disabled. This will potentially lead to issues with apps that rely on these components. We’re working on a fix.

In some cases, the notification banner for some badging will not appear in the widgets board.
