Windows 11 servicing stack update (KB5050113) - 22621.4740 and 22631.4740​

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 toSymptomWorkaround
All usersFollowing the installation of the October 2024 security update, some customers report that the OpenSSH (Open Secure Shell) service fails to start, preventing SSH connections. The service fails with no detailed logging, and manual intervention is required to run the sshd.exe process.
This issue is affecting both enterprise, IOT, and education customers, with a limited number of devices impacted. Microsoft is investigating whether consumer customers using Home or Pro editions of Windows are affected.
Customers can temporarily resolve the issue by updating permissions (ACLs) on the affected directories. Follow these steps:
  1. Open PowerShell as an Administrator.
  2. Update the permissions for C:\ProgramData\ssh and C:\ProgramData\ssh\logs to allow full control for SYSTEM and the Administrators group, while allowing read access for Authenticated Users. You can restrict read access to specific users or groups by modifying the permissions string if needed.
    Use the following commands to update the permissions:
    $directoryPath = "C:\ProgramData\ssh" $acl = Get-Acl -Path $directoryPath $sddlString = "O:BAD:PAI(A;OICI;FA;;;SY)(A;OICI;FA;;;BA)(A;OICI;0x1200a9;;;AU)" $securityDescriptor = New-Object System.Security.AccessControl.RawSecurityDescriptor $sddlString $acl.SetSecurityDescriptorSddlForm($securityDescriptor.GetSddlForm("All")) Set-Acl -Path $directoryPath -AclObject $acl
  3. Repeat the above steps for C:\ProgramData\ssh\logs.
Microsoft is actively investigating the issue and will provide a resolution in an upcoming Windows update. Further communications will be provided when a resolution or additional workarounds are available.
IT adminsDevices 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.
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.

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.

AvailableNext Step
YesNone. This update will be downloaded and installed automatically from Windows Update and Microsoft Update.
YesTo get the standalone package for this update, go to the Microsoft Update Catalog website.

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.

File information

For a list of the files that are provided in this update, download the file information for cumulative update 5050021.

For a list of the files that are provided in the servicing stack update, download the file information for the SSU (KB5050113) - versions 22621.4740 and 22631.4740.
