Windows 10 servicing stack update - 20348.677

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

Symptom

Workaround

After installing updates released May 10, 2022 on domain controllers, you might see authentication failures on the server or client for some services. These services include Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP). An issue has been found related to how the domain controller manages the mapping of certificates to machine accounts.

Note Installation of the May 10, 2022 updates on client Windows devices and non-domain controller Windows Servers will not cause this issue. This issue only affects servers that are used as domain controllers.

This issue was addressed in out-of-band updates released May 19, 2022 for installation on domain controllers in your environment. There is no action needed on the client side to address this authentication issue. To get the standalone package for these out-of-band updates, search for the KB number in the Microsoft Update Catalog. You can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager. For WSUS instructions, see WSUS and the Catalog Site. For Configuration Manger instructions, see Import updates from the Microsoft Update Catalog.

Cumulative updates:

Note You do not need to apply any previous update before installing these cumulative updates.

How to get this update

Before installing this update

Microsoft now 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.

Prerequisite:

You must install KB5005039, dated August 10, 2021, before installing the LCU.

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.
