Improvements

This security update includes quality improvements. Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.

[Windows Installer] When it repairs an application, the User Account Control (UAC) does not prompt for your credentials. After you install this update, the UAC will prompt for them. Because of this, you must update your automation scripts. Application owners must add the Shield icon. It indicates that the process requires full administrator access. To turn off the UAC prompt, set the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer\DisableLUAInRepair registry value to 1. The changes in this update might affect automatic Windows Installer repairs; see Application Resiliency: Unlock the Hidden Features of Windows Installer.
[IE mode] Pop-up windows open in the background instead of in the foreground.
[AppContainer] Printers do not work as you expect when you use them in a restricted setting, like AppContainer.
[BitLocker] You might not be able to decrypt a BitLocker data drive. This occurs when you move that drive from a newer version of Windows to an older version.
[Dual boot of Windows and Linux (known issue)] Linux might fail to start up when you turn on dual-boot setup for Windows and Linux on your device. The error message is, “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.” See the full guidance in CVE-2022-2601 and CVE-2023-40547.

If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.

Windows Server 2022 servicing stack update (KB5043167) - 20348.2696

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.
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

Available	Next Step

Next Step

Yes

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.
