    Found it. It's one of the optional updates: https://support.microsoft.com/en-us/kb/3084905

    The easiest way to find it is just tap the optional updates in Windows Update and find the one that was released on 10/12.

    Great news! Do you happen to know which update it was? I have automatic updates disabled. I installed all of the important and recommended updates. Do you know if it is one of those? I suppose I could just try, just had such a bad experience before that I'm a little nervous.

    Then were you able to re-enable Bitlocker and have it re-encrypt your drives?

    Thanks for sharing the update,

    Aaron

    Alert!

    Today's MS Windows updates have fixed the secure boot issue!

    So go into BIOS and enable Secure Boot, save config and exit, restart and...

    Boom....no....red....'Secure Boot Violation'....box!

    And.....(in my case) .... the encryption option has returned to the PC info page

    Thank you Microsoft ....slow but much appreciated.
