  • New!
    This update improves the search box experience on the taskbar. As you type in the search box, search results now appear in the search flyout box. You can also change the search experience you want for your taskbar by going to Settings > Personalization > Taskbar. For commercial customers, this update adds a new policy for IT administrators to manage how the search box on the taskbar appears in your organization. For more information, see Customizing search on the Windows 11 taskbar.

  • New!
    You can now access Windows Studio effects directly from quick settings on the taskbar for devices that have a supported neural processing unit (NPU). This makes it quick and easy to turn on and configure camera effects. These effects include Background blur, Eye contact, Automatic framing, and Audio effects (Voice focus). You can still access these effects in the Settings pages.

  • New!
    This update makes it easier to get help if you are having PC issues. You can now find Quick Assist in the Start menu’s All apps list.

  • New!
    This update introduces a touch-optimized taskbar for 2-in-1 devices that you can use as a tablet. There are two states of this taskbar: collapsed and expanded. To switch between the two states, swipe up and down on the bottom of your screen. When collapsed in tablet mode, the taskbar recedes to give you more screen space and keeps you from accidentally opening the taskbar. When expanded in tablet mode, the taskbar is optimized to be easier to use with touch. Your taskbar will automatically change to this optimized version when you disconnect or fold back the keyboard.

    This feature only works on devices that can be used as tablets and is on by default. To change that, go to Settings > Personalization > Taskbar > Taskbar behaviors. The setting is called “Optimize taskbar for touch interactions when this device is used as a tablet.” If your company manages Windows updates for your device, this feature will be off by default. Administrators can turn it on using the new commercial control for continuous innovation.

  • New!
    This update provides enhanced support for braille devices. They will continue working while you switch between Microsoft Narrator and third-party screen readers. Narrator will automatically change braille drivers. For more information, see Chapter 8: Using Narrator with braille.

  • New!
    This update also adds support for new braille displays and new braille input and output languages in Narrator. Some of the new braille displays include the APH Chameleon, the APH Mantis Q40, the NLS eReader, and many more. For more information, see Chapter 8: Using Narrator with braille.

    • Names that have special characters, such as Bluetooth & devices (“click Bluetooth and devices”) or Dial – up (“click dial hyphen up”)

    Voice now supports spin controls, thumb controls, and split buttons. You interact with these controls by using the “click” command or number overlays. This update also addresses issues that affect snapping commands that snap a window left or right. Commands that move the cursor in a text box now run instantly.

  • New!
    This update also provides voice scrolling enhancements. You can use voice to scroll to the extreme left and right on a page. You can also use continuous scrolling to the left or right like what is already present for vertical scrolling.

対象 症状 回避策
IT管理者 プロビジョニングパッケージを使用すると期待どおりに動作しないことがある。Windowsが部分的にしか構成されず、Out Of Box Experienceが終了しなかったり、予期せず再起動したりする可能性がある。 Windows 11, version 22H2にアップグレードする前に、Windowsデバイスをプロビジョニングすることができれば、この問題を防ぐことが可能。
IT管理者 複複数の大きなGBファイルのコピーに予想以上の時間がかかることがある。サーバーメッセージブロック(SMB)経由でネットワーク共有からWindows 11, Version 22H2にファイルをコピーする場合に発生しやすいものの、ローカルファイルのコピーも影響を受ける可能性がある。 この問題を軽減するために、キャッシュマネージャー(バッファードI/O)を使用しないファイルコピーツールを使用することができる。これは、以下に挙げる組み込みのコマンドラインツールを使用する。

  • robocopy \\someserver\someshare c:\somefolder somefile.img /J
  • xcopy \\someserver\someshare c:\somefolder /J


IT管理者 2023年2月14日以降にリリースされた更新プログラムが、一部のWindows Server Update Services(WSUS)サーバーからWindows 11 Version 22H2に対して提供されない可能性がある。Windows Server 2016またはWindows Server 2019からアップグレードしたWindows Server 2022サーバーが影響。アップグレード中に必要なUUPのMIMEタイプが誤って削除されることによって発生。 問題を軽減するための方法はこちらを参照。解決に向けて作業中。
全ユーザー 一部のサードパーティ製UIカスタマイズアプリを使用しているWindowsデバイスが起動しなくなることがある。影響を受けるサードパーティ製UIカスタマイズアプリは、ExplorerPatcherとStartAllBack。 アップデートをインストールする前に、サードパーティ製のUIカスタマイズアプリをアンインストールすることを推奨。StartAllBackはv3.5.6以降で問題が回避できる可能性がある。
