Microsoft's Windows 11 May update (KB5089549) introduces a new C:\Windows\SecureBoot directory to host files that facilitate migration from the legacy UEFI CA 2011 root to the UEFI CA 2023 certificate. The folder contains enterprise-focused demonstration scripts and a Detect-SecureBootCertUpdate.ps1 diagnostic; Microsoft updated documentation to clarify intent and advises ordinary users not to remove the directory or run the admin scripts.
