Go to Solution[Precision Tower 3620] 2023 Secure Boot KEK Missing
Hello, it seems Dell has not provided a PK-signed KEK to Microsoft for the Dell Precision Tower 3620. As such, updating the Secure Boot certificates to the new 2023 ones fails with Event 1803: Firmware_MissingKEKInPackage. Are there any plans from Dell to provide Microsoft with updated KEKs for this, as well as other devices? This desktop is still a very capable machine. Thank you.
@Tesla1856 The second article states "nor does it mean that these systems cannot get certificate updates from Windows Update". So pretty please?
I understand Dell doesn't want to release BIOS updates for older models, but they can sign new KEKs and I reckon that's way easier.
To add more info, the PC has accepted the db certs successfully and updated to the 2023 bootloader, but there is no KEK to replace the old one, so the PC won't be able to receive updates to the dbx.
I can't really speak for Dell, but I think you know the answer. You saw the long list of machines "they are supporting" for this, correct?
You might be interested in this.
If so, we can work here quietly in your thread. If your skill level is high, I might be able to guide you the rest of the way. For starters, I would have to see the report.

@Tesla1856 was spot on, Dell provides official list of which models will receive KEK updates and which are not.

It is NOT on this list:

But IS on this list:
https://www.dell.com/support/kbdoc/en-us/000378734/microsoft-2011-secure-boot-certificates-expiration-for-out-of-scope-platforms-for-bios-updates#Precision
So, I'm going to say the answer is NO, unfortunately it will not.
