Windows Server 2022 servicing stack update (KB5040571) - 20348.2571

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
After installing this update, you might be unable to change your user account profile picture. When attempting to change a profile picture by selecting the button Start> Settings > Account > Your info and, under Create your picture, clicking on Browse for one, you might receive an error message with error code 0x80070520.	After further investigation, we concluded this issue has very limited or no impact for this Windows version. If you encounter this issue on your device, please contact Windows support for help.
Devices might experience problems with Microsoft 365 Defender. The Network Detection and Response (NDR) service might encounter issues, resulting in an interruption of network data reporting. IT administrators may confirm they’re affected by this issue with a notification that appears in the service health page, located in the Microsoft 365 admin center. The status of NDR can also be seen in the service health page.	This issue is addressed in KB5041160.
After installing the July 9, 2024, Windows security update, you might see a BitLocker recovery screen upon starting up your device. This screen does not commonly appear after a Windows update. You are more likely to face this issue if you have the Device Encryption option enabled in Settings under Privacy & Security > Device encryption. Because of this issue, you might be prompted to enter the recovery key from your Microsoft account to unlock your drive	This issue is addressed in KB5041160.
After installing the Windows update released on or after July 9, 2024, Windows Servers might affect Remote Desktop Connectivity across an organization. This issue might occur if legacy protocol (Remote Procedure Call over HTTP) is used in Remote Desktop Gateway. Resulting from this, remote desktop connections might be interrupted. This issue might occur intermittently, such as repeating every 30 minutes. At this interval, logon sessions are lost and users will need to reconnect to the server. IT administrators can track this as a termination of the TSGateway service which becomes unresponsive with exception code 0xc0000005.	This issue is addressed in KB5044281.
After installing this update, container networking on Kubernetes might not operate as expected, preventing containers from reaching external networks or communicating between pods. It potentially impacts users setting up container networking on dev or production instances using Calico on Server 2022. Affected containers will not connect to the internet, and traffic will be blocked in host devices’ Firewall. Users may observe errors such as ‘General failure’ when pinging external addresses like ‘microsoft.com’ from within the container. People using devices with Windows Home and Pro editions are unlikely to be affected, as this issue mainly impacts servers and enterprise environments using container networking.	This issue is addressed in KB5044281.

How to get this update

Before you install 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 offline OS image servicing:

Make sure that your image includes KB5030216 (09/12/2023) or a later LCU. If not, install it on your offline media before you install the latest update. This LCU updates the SSU version to 20348.1960. That is the minimum SSU version you must have to prevent error 0x800f0823 (CBS_E_NEW_SERVICING_STACK_REQUIRED).

Install this update

To install this update, use one of the following Windows and Microsoft release channels.

Windows Update Business Catalog Server Update Services

This update will automatically sync with Windows Server Update Services (WSUS) if you configure Products and Classifications as follows:

Product: Microsoft Server operating system-21H2

Classification: Security Updates

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.
