Improvements

This security update includes improvements. When you install this KB:

  • This update addresses an issue that affects the Storage Spaces Direct (S2D) cluster. It might not come online. This occurs after a periodic password rollover. The error code is 1326.

  • This update addresses an issue that affects the Appx State Repository. When you remove a user profile, the cleanup is incomplete. Because of this, its database grows as time passes. This growth might cause delays when users sign in to multi-user environments like FSLogix.

  • This update addresses an issue that affects the Windows Remote Management (WinRM) client. The client returns an HTTP server error status (500). This error occurs when it runs a transfer job in the Storage Migration Service.

  • This update addresses an issue that affects signed Windows Defender Application Control (WDAC) policies. They are not applied to the Secure Kernel. This occurs when you enable Secure Boot.

  • This update addresses an issue that might affect the Local Security Authority Subsystem Service (LSASS). It might close sporadically. The system logs the exception 0xc0000710 in the Application Error event 1000. Because of this, the domain controller restarts unexpectedly. This issue affects read-only DCs (RODC) that also run Microsoft Defender Advanced Threat Protection (ATP). 

  • This update addresses an issue that affects the Windows Kernel. This issue is related to CVE-2023-32019. To learn more, see KB5028407.

Windows 10 servicing stack update - 17763.4121

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 KB5001342 or later, the Cluster Service might fail to start because a Cluster Network Driver is not found.

This issue occurs because of an update to the PnP class drivers used by this service.  After about 20 minutes, you should be able to restart your device and not encounter this issue. For more information about the specific errors, cause, and workaround for this issue, please see KB5003571.

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 KB5028168.
