I have about 6500 devices in our environment with various Win 10 and Win 11and I'm worried that I won't have enough time to get all these updated.  They have recently been updated to the May update.  Please let me know if the June Windows Update will take care of the boot cert issue

    Hi JTisdale​ if you may, could you share in more detail: are these domain-joined, standalone, Intune Entra only etc. 
    If you run 

    get-securebootsvn 
get-securebootuefi -decoded dbdefault 
get-secureboot -decoded db

     

     

    what is their output?

    Have you tried Microsoft recently published PowerShell scripts?

    In addition you might want to hire my MVP colleague Kaido Järvemets. He's a top-notch competent person, solving your situation at scale and swift.
