Windows 10 22H2 Preview Update KB5034203 (January 23, 2024)

Windows[English]Microsoft has released an optional cumulative (preview) update KB5034203 for Windows 10 22H2 on January 23, 2024 (D-Week). This is intended to fix numerous bugs in Windows 10 22H2. There are also adjustments for users in the EU in relation to the Digital Markets Act (DMA). Below is an overview of these updates for Windows 10.


The information on the updates can be found on the Windows 10 update history page. Please note that these updates are so-called preview updates. These are optional and must be initiated manually for download and installation by default.

Windows 10 Preview Update KB5034203

Cumulative Preview Update KB5034203 is available for Windows 10 version 22H2 (all versions). A printer installation problem is listed as fixed in the highlights. In addition, the weather display on the lock screen should show more information (whether this is a highlight, everyone has to answer for themselves). Here are the key points.

  • 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).

Below is the list of quality improvements and fixes that Microsoft has specified for the update (these will be included in the security update for the following month).

  • 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.

The update is optional and is offered via Windows Update if the user explicitly searches for updates on the Settings page and then selects the optional update for download and installation. The update can also be downloaded and installed from the Microsoft Update Catalog. The latest Servicing Stack Update (SSU) is integrated. Microsoft lists known problems with this update in the support article.
