  • NetJoinLegacyAccountReuse: The update KB5041571 clears this registry key.
  • Secure Boot Advanced Targeting (SBAT) and Linux Extensible Firmware Interface (EFI): The update applies SBAT to systems that run Windows, which stops vulnerable Linux EFI (Shim bootloaders) from running.

Microsoft combines the latest servicing stack update (SSU) with the latest cumulative update (LCU). Windows 11 servicing stack update (SSU) KB5041575 makes quality improvements to the servicing stack – the component that installs Windows updates.

SSU can provide you with a robust and reliable servicing stack so that your devices can receive and install Microsoft updates. You can remove the LCU after installing the combined SSU and LCU package. To do that, utilize the DISM/Remove-Package command line option with the LCU package name as the argument. Find the package name by executing this command: DISM /online /get-packages

Since the combined package contains the SSU, running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package won’t work.
