Summary
This update makes improvements to Windows setup binaries or any files that setup uses for feature updates in Windows 11, version 23H2. The following is a summary of the issues that this update addresses when you install this update. The bold text within the brackets indicates the item or area of the change we are documenting.
-
[Secure Boot] This release will execute updates in the Boot Manager on devices that already have the Windows UEFI CA 2023 certificate in their Secure Boot Signature Database (DB). It replaces the 2011 signed bootmgfw.efi with the 2023 signed bootmgfw.efi. Be advised of the consequences of resetting the DB or toggling Secure Boot, as this can cause a "Secure Boot violation" issue. In those rare cases, the solution is to create the Secure Boot recovery media.
