Secure Boot Problem.


Did your BIOS Secure Boot settings change when you updated, or was the Custom setting with reference to the KEK something new?
Within the BIOS itself, nothing changed after the update. I left the switch to Custom settings in place and did not revert back to original Standard. I could not see a reason to revert back.

Within, Windows 11, the update changed Device Security - Secure Boot to "Secure Boot is on and all required certificate updates have been applied. No further certificate changes are needed."

A reminder, about 24 hours was needed before Microsoft did the update after my settings change.
