Event details
Trying to keep tabs on progress of cert rollout, I had a Dell device initiate the cert update process after applying the May LCU but with an oddity:
After reboot and waiting for the scheduled task to run, AvailableUpdates=0x4100 but UEFICA2023Status=NotStarted. I've never seen this combination, which skews reporting. 0x4100 is usually accompanied with InProgress status.
TPM-WMI event cadence looks normal with 1036/1044/1045/1043 then 1801 re: pending reboot (Reason: Boot Manager (2023)).
Get-SecureBootUEFI confirms 2023 certs are reflected in the db and kek variables.
So if the intention is to rely on UEFICA2023Status, am I missing something or does something seem off here? Any thoughts or direction would be most appreciated.

jad I have not seen this before. Two questions:
- Did you initiate the updates or was this done automatically as a high confidence update?
- Which version of Windows is this?
I'll check with our team to see if they know why.

Many thanks for the reply, Arden_White To answer your questions:
- No, I did not initiate the cert updates -- the update was applied on reboot after applying May updates so I anticipate LCU was the update mechanism.
- Yes, ConfidenceLevel=High Confidence in registry. Was "Under Observation..." prior to applying the May LCU.
- OS is Windows 11 24H2.
