Windows 11 servicing stack update (KB5050108) - 26100.3023
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 | Symptom | Workaround |
|---|---|---|
| All users | We’re aware of an issue where players on Arm devices are unable to download and play Roblox via the Microsoft Store on Windows. | Players on Arm devices can play Roblox by downloading the title directly from www.Roblox.com. |
| All users | Following 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:

| IT admins | 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. | 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. |
