Microsoftは本日、Windows 10 22H2 Build 19045.4713(KB5040525)をリリースしました(Windows Blog)。

Windows Insider Programの更新オプションでBeta/Release Previewチャンネルを選択し、Windows 10 Version 22H2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。

BetaチャンネルとRelease Previewチャンネルには同じWindows 10ビルドが提供されますが、Betaチャンネルでは、まだすべてのWindows 10ユーザーに提供する準備が整っていない新機能のテストが行われる予定です。

Build 19045.4713では、ブラウザがHKLM\SOFTWARE\Microsoft\Internet Explorer\MainにあるFrameShutdownDelayを無視する問題の修正や、グループポリシーエディタ(Wi-Fi Protected Access 3 (WPA3))で、HTMLプレビューのレンダリングに失敗する問題の修正、TCPの送信コードにより、ファイル転送などのルーチン・タスク中にシステムが応答しなくなることがある問題の修正などが行われています。

リリースノートは以下の通りです。

[FrameShutdownDelay] The browser ignores its value in the “HKLM\SOFTWARE\Microsoft\Internet Explorer\Main” registry key.

[Wi-Fi Protected Access 3 (WPA3)] In the Group Policy editor, HTML preview rendering fails.

[Group Policy Preferences Item Level Targeting (ILT) and Local Users and Groups] You cannot choose a group from the target domain for ILT. Also, you cannot choose an account from Local Users and Groups. The forest does not appear. This issue occurs when you deploy multiple forests, and the target domain has a one-way trust with the domain of the admin. This issue affects Enhanced Security Admin Environment (ESAE), Hardened Forests (HF), or Privileged Access Management (PAM) deployments.

[Transmission Control Protocol (TCP)] The TCP send code often causes a system to stop responding during routine tasks, such as file transfers. This issue leads to an extended send loop.

[Print Support App] When you use the app with a USB device, the app stops responding and does not print. This issue also limits the functions of the user interface.

[Universal Print clients] They fail to communicate with the Universal Print service. This affects printing functions. This issue occurs when you turn on Web Proxy Auto Discovery (WPAD).

[Windows Defender Application Control (WDAC)]

This update prevents a stop error that occurs when you apply more than 32 policies.

A memory leak occurs that might exhaust system memory as time goes by. This issue occurs when you provision a device.

WDAC fails to verify the policies of some apps.

[Windows Kernel Vulnerable Driver Blocklist file (DriverSiPolicy.p7b)] This update adds to the list of drivers that are at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks.

[Windows Backup] Backup sometimes fails. This occurs when a device has an Extensible Firmware Interface (EFI) system partition (ESP).

[DHCP Option 235 (known issue)] Some Windows devices use this option to find Microsoft Connected Cache (MCC) nodes in their network. But you might not be able to use these nodes when you find them. Instead, these devices download updates and apps from the public internet. Because of this, download traffic increases.
