Highlights​

  • Updates an issue that might cause video subtitles to be partially cut off.
  • Updates an issue that incorrectly aligns video subtitles.
  • Displays the temperature on top of the weather icon on the taskbar.
  • Updates an issue that prevents you from using the minimize, maximize, and close buttons on a maximized app window.

Improvements​

This non-security update includes quality improvements. Key changes include:
  • New! Adds improvements for servicing the Secure Boot component of Windows.
  • Addresses an issue that causes the AppX Deployment Service (AppXSvc) to stop working after you install certain MSIX apps.
  • Addresses a race condition that occurs early in the startup process that might cause a stop error.
  • Improves the Autopilot client to process updated Trusted Platform Module (TPM) capabilities that support self-deployment and pre-provisioning scenarios.
  • Changes the timeout for Azure Active Directory (Azure AD) registration from 60 minutes to 90 minutes for hybrid Azure AD-joined Autopilot scenarios. This also addresses a race condition that causes an exception at timeout.
  • Addresses an issue in which certain Point of Sale terminals experience occasional OS startup delays during restart of up to 40 minutes.
  • Addresses a memory leak issue that affects Windows systems that are in use 24 hours each day of the week.
  • Addresses an issue that affects the Dynamic Host Configuration Protocol (DHCP) option 119 (Domain Search Option) by preventing the use of the connection-specific DNS Suffix Search List.
  • Addresses an issue that affects the Title attribute in Microsoft Ege IE mode.
  • Addresses an issue in which mobile device management (MDM) policies were not allowed on Windows Enterprise editions that were upgraded to Enterprise using Azure AD-joined subscription entitlement.
  • Addresses an issue that might cause video subtitles to be partially cut off.
  • Addresses an issue that incorrectly aligns video subtitles.
  • Addresses an issue that causes Kerberos authentication to fail, and the error is “0xc0030009 (RPC_NT_NULL_REF_POINTER)”. This occurs when a client machine attempts to use the Remote Desktop Protocol (RDP) to connect to another machine while Remote Credential Guard is enabled.
  • Addresses an issue that causes Windows to go into BitLocker recovery after a servicing update.
  • Addresses an issue that prevents retrieval of the Endorsement Key (EK) certificate from the TPM device.
  • Addresses an issue that might fail to copy the security portion of a Group Policy to a machine.
  • Addresses an issue that prevents the instantiation of the Microsoft RDP Client Control, version 11 and higher, inside a Microsoft Foundation Class (MFC) dialog.
  • Displays the temperature on top of the weather icon on the taskbar.
  • Addresses an issue that prevents you from using the minimize, maximize, and close buttons on a maximized app window. This issue occurs because the Notification Center keeps the input focus.
  • Addresses an issue that might occur when you use Netdom.exe or the Active Directory Domains and Trusts snap-in to list or modify name suffixes routing. These procedures might fail. The error message is, "Insufficient system resources exist to complete the requested service." This issue occurs after installing the January 2022 security update on the primary domain controller emulator (PDCe).
  • Addresses an issue that causes the primary domain controller (PDC) of the root domain to generate warning and error events in the System log. This issue occurs when the PDC incorrectly tries to scan outgoing-only trusts.
  • Addresses an issue that occurs when you map a network drive to a Server Message Block version 1 (SMBv1) share. After restarting the OS, you cannot access that network drive.
  • Addresses an issue that affects an SMB multichannel connection and might generate a 13A or C2 error.
  • Addresses an issue that damages a pool when a Client-Side Caching (CSC) cleanup method fails to delete a resource that was created.
  • Addresses an issue that might cause the server to lock up because the nonpaged pool grows and uses up all memory. After a restart, the same issue occurs again when you try to repair the damage.
  • Reduces the overhead of resource contention in high input/output operations per second (IOPS) scenarios that have many threads contending on a single file.
If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.

Windows 11 servicing stack update - 22000.652​

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

Known issues in this update​

Applies toSymptomWorkaround
IT adminsAfter installing the Windows updates released January 11, 2022 or later Windows versions on an affected version of Windows, recovery discs (CD or DVD) created by using the Backup and Restore (Windows 7) app in Control Panel might be unable to start.

Recovery discs that were created by using the Backup and Restore (Windows 7) app on devices which have installed Windows updates released before January 11, 2022 are not affected by this issue and should start as expected.

Note No third-party backup or recovery apps are currently known to be affected by this issue
We are working on a resolution and will provide an update in an upcoming release.
IT adminsAfter installing this update, some .NET Framework 3.5 apps might have issues or might fail to open. Affected apps are using certain optional components in .NET Framework 3.5, such as Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.To mitigate this issue, you can uninstall this update. To do this, select the Start button and type, Windows Update Settings, and select it. On the Windows Update settings window, select View Update History then select Uninstall Update. Find KB5012643 in the list and select it, then select Uninstall.

If you cannot uninstall this update (KB5012643), you can also mitigate this issue by re-enabling .NET Framework 3.5 and the Windows Communication Foundation in Windows Features. For instructions, please see Enable the .NET Framework 3.5 in Control Panel. Advanced users or IT admins can do this programmatically using an elevated Command Prompt (run as administrator) and running the following commands:

dism /online /enable-feature /featurename:netfx3 /all

dism /online /enable-feature /featurename:WCF-HTTP-Activation

dism /online /enable-feature /featurename:WCF-NonHTTP-Activation

We are working on a resolution and will provide an update in an upcoming release.
IT adminsDevices starting in Safe Mode might show a flickering screen. Components that rely on explorer.exe, such as File Explorer, the Start menu, and the taskbar, can be affected and appear unstable.

Devices experiencing this issue can log a System error on the Windows Event Log, with Source “Winlogon” and the following description: “The shell stopped unexpectedly and explorer.exe was restarted.”
This issue is addressed using Known Issue Rollback (KIR) and will be resolved automatically for most consumer and non-managed business devices. Please note that it might take up to 24 hours for the resolution to propagate. Restarting your device might help the resolution be applied faster. For managed devices, additional steps and guidance on the manual application of the KIR are available on the known issue entry in the Windows release health dashboard.

If applying the KIR is not an option for your device, the issue can be prevented by entering Safe Mode with Networking (Safe Mode without Networking may result in this issue). Please refer to this document for more details on how to start your device in Safe Mode with Networking: Start your PC in safe mode in Windows (microsoft.com)
