Windows 10 servicing stack update (KB5043130) - 19045.4950

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.

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 this update, you might experience a black screen when you login to Azure Virtual Desktop (AVD). You might also notice that you are unable to log out of your account and the black screen persists even after disconnecting and reconnecting to AVD. Resulting from this issue, the application event log in Event viewer will show an application error with Event ID:1000 indicating a fault with the application ‘svchost.exe_AppXSvc’.

Please note that AppX Deployment Service (AppxSvc) being in an invalid state could also cause other symptoms like the Start Menu to close unexpectedly due to registration issues.

This issue is resolved by installing the Windows updates released October 22, 2024 (KB5045594) or later updates and by applying one of the options mentioned in the Resolution section in KB5048864. Note that you need to perform both actions to resolve the issue.

After installing this update or later, you might observe that apps such as Quick Assist, Microsoft Teams, Windows Narrator, etc. might fail to start if you are a non-admin user. You might experience this issue on any app that sets UIAccess=true while trying to run the app as a non-admin user. The uiAccess=true attribute in an application's manifest file is used to request that the application be granted higher privileges. Apps using this attribute launch from a secure path, such as:

  • %ProgramFiles% (including subdirectories)

  • %ProgramFiles(x86)% (including subdirectories for 64-bit versions of Windows)

  • %systemroot%\system32

  • %systemroot%\syswow64 (for 64-bit versions of Windows)

If you have the Procmon monitoring tool installed in your device, you will observe that the application runs with the wrong integrity level, Integrity:Low instead of the expected Integrity:Medium. You are less likely to encounter this issue if you are running the application as an administrator.

This issue is mitigated using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the resolution to propagate automatically to consumer devices and non-managed business devices and business devices that are not managed by IT departments. Restarting your Windows device might help the resolution apply to your device faster. 

For enterprise-managed devices managed by IT departments that have installed the affected update and encountered this issue, IT administrators can resolve it by applying the KIR mentioned in the resolution section of Windows release health dashboard for this issue. 

After installing this update, or subsequent updates, a small subset of Azure Virtual Desktop customers using multi-session hosts (AVD) may experience the following issues:  ​​​

  • An extended 10-to-30-minute-long hang at a black screen following user logon.

  • Office applications including Outlook and Teams experience single sign-on (SSO) failures, preventing users from connecting or synchronizing data.​​​​​​​

This issue is caused by a deadlock in the interactions between the Azure Active Directory (AAD) broker and the underlying AppX deployment service(AppxSvc) and Background tasks infrastructure service. You are more likely to experience this issue if you are using FSLogix user profile containers on multi-session environments. FSLogix is a Microsoft tool that helps manage and speed up user profiles on computers, especially in virtual environments like remote desktops.

This issue is resolved by installing the Windows updates released October 22, 2024 (KB5045594) or later updates and by applying one of the options mentioned in the Resolution section in KB5048864. Note that you need to perform both actions to resolve the issue.

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:

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

  1. For offline OS image servicing:

    If your image does not have the July 25, 2023 (KB5028244) or later LCU, you must install the special standalone Oct 13, 2023 SSU (KB5031539) 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.

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.
