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:

Based on your installation scenario, choose one of the following:

  1. For offline OS image servicing:

    If your image does not have the July 25, 2023 (KB5028244) or later LCU, you must install the special standalone Oct 13, 2023 SSU (KB5031539) before installing this update.

  2. For Windows Server Update Services (WSUS) deployment or when installing the standalone package from Microsoft Update Catalog: 

    If your devices do not have the May 11, 2021 (KB5003173) or later LCU, you must install the special standalone August 10, 2021 SSU (KB5005260) before installing this update.
