Windows 11 servicing stack update (KB5053665) - 22621.5120 and 22631.5120​

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. To learn more about SSUs, see Simplifying on-premises deployment of servicing stack updates.

Known issues in this update​

Applies to: All users

Symptom
Devices that have certain Citrix components installed might be unable to complete installation of the January 2025 Windows security update. This issue was observed on devices with Citrix Session Recording Agent (SRA) version 2411. The 2411 version of this application was released in December 2024.

Affected devices might initially download and apply the January 2025 Windows security update correctly, such as via the Windows Update page in Settings. However, when restarting the device to complete the update installation, an error message with text similar to “Something didn’t go as planned. No need to worry – undoing changes” appears. The device will then revert to the Windows updates previously present on the device.

This issue likely affects a limited number of organizations as version 2411 of the SRA application is a new version. Home users are not expected to be affected by this issue.

Workaround
Citrix has documented this issue, including a workaround, which can be performed prior to installing the January 2025 Windows security update. For details, see Citrix’s documentation.

Microsoft is working with Citrix to address this issue and will update this documentation once a resolution is available.


Symptom

Audit Logon/Logoff events in the local policy of the Active Directory Group Policy might not show as enabled on the device even if they are enabled and working as expected. This can be observed in the Local Group Policy Editor or Local Security Policy, where local audit policies show the "Audit logon events" policy with Security Setting of "No auditing".

This issue might only manifest as a reporting inconsistency. It’s possible that logon events are correctly being audited on the device. However, the “Audit logon events” policy will reflect that this is not the case. Home users are unlikely to be affected by this issue, as logon auditing is generally only necessary in enterprise environments.

Workaround

This issue was resolved by Windows update released April 11, 2025 (KB5058919). To keep your device performing at its best, make sure you have the latest update for your device. It contains important improvements and issue resolutions.

How to get this update​

Before you install this update

Microsoft 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.

Install this update

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


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.
