Windows 11 servicing stack update - 22000.1270

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

Applies to

Symptom

Workaround

All users

The Start menu, Windows search, and Universal Windows Platform (UWP) apps might not work as expected or might have issues opening. Affected Windows devices might have damaged registry keys or data which might affect apps using Microsoft Office APIs to integrate with Windows, Microsoft Office, or Microsoft Outlook or Outlook Calendar. An example of an app affected by this issue is ClickShare. The underlying Issue is not caused by the installation of an update to Windows and might be exposed by an update to an affected app.

To mitigate this issue, you can uninstall apps which integrate with Windows, Microsoft Office, Microsoft Outlook or Outlook Calendar. Updates to affected apps or guidance from the developer of the app might also be available. If you are using ClickShare by Barco, please see Symptom: Start Menu and other shell components fail when Apps including Barco's ClickShare access Office APIs and Unresponsive Windows taskbar or user shell folder permissions issues with ClickShare App Calendar integration.

We are presently investigating and will provide additional information as it becomes available.

IT admins

After installing updates released January 10, 2023, and later, kiosk device profiles that have auto log on enabled might not sign in automatically. After Autopilot completes provisioning, affected devices will stay on the sign-in screen prompting for credentials.

This issue is addressed in KB5025224.
