January 23, 2024—KB5034203 (OS Build 19045.3996) Preview

Windows 10 Version 22H2用の更新プログラムKB5034203では、一部の単機能プリンターがスキャナとしてインストールされる可能性がある問題の対処や、ロック画面の新しい天気ウィジェットの導入、欧州経済地域(EEA)におけるデジタル市場法(DMA)の遵守のための変更などが行われています。



  • This update addresses an issue that affects some single-function printers. They might install as a scanner.

  • New!
    The coming weeks will bring a richer weather experience to your lock screen. This includes dynamic, interactive weather updates. So, as you hover over the weather on your lock screen, you will see more information. When you tap or click on the weather card and sign in, Microsoft Edge opens with the full forecast in MSN weather. If you already use Weather in Settings > Personalization > lock screen > Lock screen status, there is nothing for you to do. Also, this new experience will be on by default if Lock screen status is set to “None.” Like today, lock screen status will be available when you lock your screen no matter which personalization option you select (Windows spotlight, Picture, or Slideshow).


  • Microsoft has been working to ensure compliance with the Digital Markets Act (DMA) in the European Economic Area (EEA). To learn more, see Previewing changes in Windows to comply with the Digital Markets Act in the European Economic Area. These changes will gradually roll out to Windows 10, version 22H2 PCs in the EEA to be compliant by March 6, 2024.

  • This update addresses an issue that affects an Internet Explorer shortcut. After you use a policy to remove it, the shortcut reappears.

  • This update addresses an issue that affects Windows Management Instrumentation (WMI). A caching issue occurs. The issue causes CurrentTimeZone to change to the wrong value.

  • This update addresses an issue that affects XPath queries on FileHash and other binary fields. It stops them from matching values in event records.

  • This update addresses a known issue that affects BitLocker data-only encryption. A mobile device management (MDM) service, such as Microsoft Intune, might not get the right data. This occurs when you use the FixedDrivesEncryptionType or SystemDrivesEncryptionType policy settings in the BitLocker configuration service provider (CSP) node.

  • This update addresses an issue that affects the Code Integrity Module (ci.dll). This issue stops your device from responding.

  • This update includes quarterly changes to the Windows Kernel Vulnerable Driver Blocklist file, DriverSiPolicy.p7b. It adds to the list of drivers that are at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks.

  • This update affects Unified Extensible Firmware Interface (UEFI) Secure Boot systems. It adds a renewed signing certificate to the Secure Boot DB variable. You can now opt for this change.

  • This update addresses an issue that stops you from reconnecting to an existing Remote Desktop session. Instead, you get a new one.

  • This update addresses an issue that occurs when you change the keyboard language. The change fails to apply to RemoteApps in some scenarios.

  • This update addresses an issue that affects Windows Local Administrator Password Solution (LAPS) Post Authentication Actions (PAA). The actions occur at restart instead of at the end of the grace period.

  • This update addresses an issue that affects Active Directory. Bind requests to IPv6 addresses fail. This occurs when the requestor is not joined to a domain.

  • This update addresses an issue that affects the LocalUsersAndGroups CSP. It stops processing group memberships if it cannot find a group.

  • This update addresses an issue that affects deleted cloud files. When a cloud provider vetoes a deletion request, the files might still be removed.

  • This update addresses an issue that affects MSIX applications. They do not open, and, in some cases, they make the host unresponsive. This occurs when they use MSIX App Attach with a CimFS image.

  • This update addresses an issue that affects Group Policy Folder Redirection in a multi-forest deployment. The issue stops you from choosing a group account from the target domain. Because of this, you cannot apply advanced folder redirection settings to that domain. This issue occurs when the target domain has a one-way trust with the domain of the admin user. This issue affects all Enhanced Security Admin Environment (ESAE), Hardened Forests (HF) or Privileged Access Management (PAM) deployments.

  • This update changes a setting in Active Directory Users & Computers. By default, the snap-in now uses a strong certificate mapping of X509IssuerSerialNumber. It does not use the weak mapping of x509IssuerSubject.


症状 回避策
1台以上のモニターを使用しているWindowsデバイスでは、WindowsでCopilotを使用しようとすると、モニター間でデスクトップアイコンが予期せず移動したり、アイコンの位置がずれたりする問題が発生する場合がある。 ユーザーがこの問題に遭遇しないように、Windows Copilotは、マルチモニター構成デバイスでは使用できない場合がある。現在こ問題の解決に向けて取り組んでいる。
Windows Copilotは、タスクバーが画面の右または左に垂直に配置されている場合、サポートされていない。 WindowsでCopilotにアクセスするには、タスクバーが画面の上部または下部に水平に配置されていることを確認する。現在、解決に向けて取り組んでおり、次回のリリースで最新情報を提供する予定。
