  1. Windows 11 revocations


    I applied the revocations to one Windows 11 computer. Later when needed, how will a bios update affect the revocations? Reference:https://support.microsoft.com/en-us/topic/kb5025885-how-to-manage-the-windows-boot-manager-revocations-for-secure-boot-changes-associated-with-cve-2023-24932-41a975df-beb2-40c1-99a3-b3ff139f832d#bkmk_mitigation_guidelinesAnd one more question, in the fixing boot media they have this line:bcdboot c:\windows /f UEFI /s D: /bootexWhat is /bootex?

  2. How to check that the UEFI DBX revocation list is in good state ? (Error message while updating UEFI DBX revocation list )

    I did an update of the UEFI DBX revocation list in windows 11 (build 22361) but I get an error message . The update was the following :

    "Microsoft guidance for applying Secure Boot DBX update (KB4575994)".

    But after this I get an error message (something like the text : "system.date not ok .....) . I did all instructions but the first instruction did generate the error message. Now I presume that the revocation list is damaged.

    I am a Windows Insider of the Release Preview Channel and currently have build 22361.2861 (release 23H2) , with TPM module enabled. I do not have any problems except that I do not know wether this revocation list is damaged or not.

    How can I reset this UEFI DBX revocation list in Windows ? My target is that I want to have the UEFI DBX revocation list in good state. Not important it is last version or not (preferably last version of course) . If not possible to reset : how can I know in Windows the state of the UEFI revocation list ?

  4. Windows 11 revocations

    Using Bcdboot repair after appling Windows Boot Manager revocations for Secure Boot changes

    The revocations aren't affected even if I reformat the efi partition prior to using Bcdboot?

    I did all of this and it booted fine, but there isn't any revocation code stored on the efi partition? I am just double checking this stuff. I thought the revocations list was too big to store everything inside the bios chip.

    Sorry for being a stickler for details.
