8/26/22 REMINDER Windows Server, version 20H2 reached end of service on August 9, 2022. These devices no longer receive monthly security and quality updates that contain protection from the latest security threats. To continue receiving security and quality updates, Microsoft recommends updating to the latest version of Windows Server.

We will continue to service the following editions: Windows 10 Enterprise and Education, Windows 10 IoT Enterprise, Windows 10 Enterprise multi-session, and Windows 10 on Surface Hub. 

5/10/22 REMINDER To update to one of the newer versions of Windows 10, we recommend that you use the appropriate Enablement Package KB (EKB). Using the EKB makes updating faster and easier and requires a single restart. To find the EKB for a specific OS, go to the Improvements section and click or tap the OS name to expand the collapsible section.

Windows 10 servicing stack update - 19042.1940, 19043.1940, and 19044.1940

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

Symptoms

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 this update, file copies using Group Policy Preferences might fail or might create empty shortcuts or files using 0 (zero) bytes. Known affected Group Policy Objects are related to files and shortcuts in User Configuration > Preferences > Windows Settings in Group Policy Editor.

This issue was addressed in KB5018410. Installation of this update prevents and resolves this issue, but if any workaround was used to mitigate this issue, it will need to be changed back to the original configuration.

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:

Based on your installation scenario, choose one of the following:

  1. For offline OS image servicing:

    If your image does not have the March 22, 2022 (KB5011543) or later LCU, you must install the special standalone May 10, 2022 SSU (KB5014032) before installing this update.

  2. 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 (KB5003173) or later LCU, you must install the special standalone August 10, 2021 SSU (KB5005260) before installing this update.

Windows Server Update Services (WSUS)

No

You can import this update into WSUS manually. See the Microsoft Update Catalog for instructions.

If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.

Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
