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.

  • [Absent apps and features] Some apps and features are absent after you upgrade to Windows 11.

  • ​​​​​​​[Double-wide character set range] This update adds new ranges to the double-wide character set range. This ensures that the PowerShell console identifies and handles them the right way.

  • [Input Method Editor (IME)] The candidate list fails to show or shows in the wrong position.

  • [Windows Presentation Foundation (WPF)] A malformed Human Interface Device (HID) descriptor causes WPF to stop responding.

  • [Remote Desktop Session Host (RDSH)] Users cannot connect to the RDSH. This occurs because dwm.exe stops responding.

  • [Remote Desktop MultiPoint Server​​​​​​​] A race condition causes the service to stop responding.

  • [Windows Local Administrator Password Solution (LAPS)] Its Post Authentication Actions (PAA) do not occur at the end of the grace period. Instead, they occur at restart.

  • [Remote Authentication Dial-In User Service (RADIUS) protocol] This issue is related to MD5 collisions. For more information, see KB5040268.

  • [BitLocker] This update adds PCR 4 to PCR 7 and 11 for the default Secure Boot validation profile. See CVE-2024-38058 for more information.

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 (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. 

We are working on a resolution and will provide an update in an upcoming release.

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.

To work around this issue, use one of the following options:

Option 1: Disallow connections over pipe, and port \pipe\RpcProxy\3388 through the RD Gateway.

This process will require the use of connection applications, such as firewall software. Consult the documentation for your connection and firewall software for guidance on disallowing and porting connections.

Option 2: Edit the registry of client devices and set the value of RDGClientTransport to 0x00000000 (0)

In Windows Registry Editor, navigate to the following registry location:

HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client

Find RDGClientTransport and set its value to 0 (zero). This changes the value of RDGClientTransport to 0x00000000 (0).

Next step: We are working on a resolution and will provide an update in an upcoming release.

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 documentation contains information about how to modify the registry. Make sure that you back up the registry before you modify it and that you know how to restore the registry if a problem occurs. For more information, see How to back up and restore the registry in Windows.

To mitigate the issue temporarily until a resolution is available, please follow the below steps:

a. Add a registry value to disable the changes by running the following command:

reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hns\State /v FwPerfImprovementChange /t REG_DWORD /d 0 /f

b. Restart the hns service by running the command:

Restart-service hns

We are working on a resolution that will be available in a future Windows update.

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).

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.
