How to get this update

Special instructions for Windows Recovery Environment (WinRE) devices - updated 1/20/23

Devices with Windows Recovery Environment (WinRE) will need to update the WinRE partition to address security vulnerabilities in CVE-2022-41099. Installing the update normally into Windows will not address this security issue in WinRE. For guidance on how to address this issue in WinRE, please see CVE-2022-41099.

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.

If you want to remove the LCU

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.
