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
Microsoft is not currently aware of any issues with this update.
How to get this update
Special instructions for Windows Recovery Environment (WinRE) devices
Devices with Windows Recovery Environment (WinRE) will need to update both Windows and WinRE 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 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
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.
