Windows 10 servicing stack update - 19042.1704, 19043.1704, and 19044.1704

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

Symptom

Workaround

Devices with Windows installations created from custom offline media or custom ISO image might have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.

Note Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the SSU and latest cumulative update (LCU) without any extra steps. 

To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the SSU:

  1. Extract the cab from the msu via this command line (using the package for KB5000842 as an example): expand Windows10.0-KB5000842-x64.msu /f:Windows10.0-KB5000842-x64.cab <destination path>

  2. Extract the SSU from the previously extracted cab via this command line: expand Windows10.0-KB5000842-x64.cab /f:* <destination path>

  3. You will then have the SSU cab, in this example named SSU-19041.903-x64.cab. Slipstream this file into your offline image first, then the LCU.

If you have already encountered this issue by installing the OS using affected custom media, you can mitigate it by directly installing the new Microsoft Edge. If you need to broadly deploy the new Microsoft Edge for business, see Download and deploy Microsoft Edge for business.

After installing the June 21, 2021 (KB5003690) update, some devices cannot install new updates, such as the July 6, 2021 (KB5004945) or later updates. You will receive the error message, "PSFX_E_MATCHING_BINARY_MISSING".

For more information and a workaround, see KB5005322.

After 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

This issue is addressed in KB5014023.

We are receiving reports that the Snip & Sketch app might fail to capture a screenshot and might fail to open using the keyboard shortcut (Windows key+shift+S). This issue occurs after installing KB5010342 (February 8, 2022) and later updates.

This issue is addressed in KB5014666.

After installing this update, Windows devices that use certain GPUs might cause apps to close unexpectedly or cause intermittent issues that affect some apps that use Direct3D 9. You might also receive an error in Event Log in Windows Logs/Applications, and the faulting module is d3d9on12.dll and the exception code is 0xc0000094.

This issue is addressed in KB5014023. If you can't install KB5014023, see the instructions below.

This issue is addressed using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the KIR to propagate automatically to consumer devices and non-managed business devices. Restarting your Windows device might help the KIR apply to your device faster. For enterprise-managed, devices that have installed an affected update and encountered this issue can address it by installing and configuring the special Group Policy listed below. For information on deploying and configuring these special Group Policies, seeHow to use Group Policy to deploy a Known Issue Rollback.

Important You must install and configure the Group Policy to address this issue. Please see, How to use Group Policy to deploy a Known Issue Rollback.

Updated May 27, 2022

After installing updates released May 10, 2022 on your domain controllers, you might see machine certificate authentication failures on the server or client for services such as Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP). An issue has been found related to how the mapping of certificates to machine accounts is being handled by the domain controller.

Note Installation of updates released May 10, 2022, on client Windows devices and non-domain controller Windows Servers will not cause this issue. This issue only affects installation of May 10, 2022, updates installed on servers used as domain controllers.

Updated May 27, 2022

The preferred mitigation for this issue is to manually map certificates to a machine account in Active Directory. For instructions, please see Certificate Mapping.

Note The instructions are the same for mapping certificates to user or machine accounts in Active Directory. If the preferred mitigation will not work in your environment, please see KB5014754—Certificate-based authentication changes on Windows domain controllers for other possible mitigations in the SChannel registry key section.

Note Any other mitigation except the preferred mitigations might lower or disable security hardening.

This issue was addressed in out-of-band updates released May 19, 2022 for installation on all Domain Controllers in your environment, as well as all intermediary application servers such as Network Policy Servers (NPS), RADIUS, Certification Authority (CA), or web servers which passes the authentication certificate from the client being authenticated to the authenticating DC. If you used any workaround or mitigations for this issue, they are no longer needed, and we recommend you remove them. This includes the removal of the registry key (CertificateMappingMethods = 0x1F) documented in the SChannel registry key section of KB5014754. There is no action needed on the client side to resolve this authentication issue.

To get the standalone package for these out-of-band updates, search for the KB number in the Microsoft Update Catalog. You can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager. For WSUS instructions, see WSUS and the Catalog Site. For Configuration Manger instructions, see Import updates from the Microsoft Update Catalog. Note The below updates are not available from Windows Update and will not install automatically.

Cumulative updates:

Note You do not need to apply any previous update before installing these cumulative updates. If you have already installed updates released May 10, 2022, you do not need to uninstall the affected updates before installing any later updates including the updates listed above.

After installing this update, you might receive an error code: 0xC002001B when attempting to install from the Microsoft Store. Some Microsoft Store apps might also fail to open. Affected Windows devices use a processor (CPU) which supports Control-flow Enforcement Technology (CET), such as such as 11th Gen and later Intel® Core™ Processors or later and certain AMD processors.

This issue was addressed in the out-of-band update KB5015020. It is a cumulative update, so you do not need to apply any previous update before installing it. To get the standalone package for KB5015020, search for it in the Microsoft Update Catalog. You can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager. For WSUS instructions, see WSUS and the Catalog Site. For Configuration Manger instructions, see Import updates from the Microsoft Update Catalog.

Note KB5015020 is not available from Windows Update and will not install automatically.

How to get this update

Before installing this update

Microsoft now combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

Prerequisite:

For Windows Server Update Services (WSUS) deployment or when installing the standalone package from Microsoft Update Catalog:

If your devices do not have the May 11, 2021 update (KB5003173) or later LCU, you must install the special standalone August 10, 2021 SSU (KB5005260).
