Did you manually update your Secure Boot Keys ?


I ran those MoKiChU scripts. and now i have all 2023 CAs and eventviewer has Information (not Error anymore) event-ID 1808 which starts with This device has updated Secure Boot CA/keys.

It's good to know that whether manually (official kb)/windows update and manually mosby/MoKiChU scripts, windows detects it and displays it in the event viewer.

Edit: rather later via windows update or manually official it will be detected by the event viewer, for now no.

I have the 2023 certs installed as my system is recent... but it's booting off the 2011 cert:

How do I move to using the 2023 certificate and moving the 2011 cert to the DBX list?

See here:

How to manage the Windows Boot Manager revocations for Secure Boot changes associated with CVE-2023-24932

The steps in #2 will verify what you have. Be VERY sure everything looks right and is working properly before revoking the 2011 CA. Check all bootable flash drives, etc,

We are running servers using VMware. The KEK cert we enrolled manually (because the windows task scheduled failed to do so), while the other 3 certs are added successfully after running the task schedule. However we still getting Event ID 1801 instead of Event ID 1808, similar to what some people are also facing here in this forum.

I got this new BIOS update notice from Dell this morning that contains the new 2023 Secure Boot Certificates. So, it looks like Dell, at least, is starting to push these certificates out. This update is for my System One, I have not checked for my System Two machine yet.

I have not downloaded and installed this BIOS yet; I normally wait a week after Dell releases a new BIOS before I download and install it.

    The Samsung NVMe PM9C1a 1024GB SSD does not use a Phison NAND controller. Instead, it uses Samsung's in-house developed Piccolo (S4LY022) 6-Core 4 Channel Controller. The PM9C1a utilizes a controller built using Samsung's 5-nanometer process and seventh-generation V-NAND technology. 🤔

It's easy to update the USB bootable drives after the fact. You should, obviously, do that right away and not wait until you need them. :giggle:

Oddly, I have Defender enabled and have never bypassed anything, I updated probably half a dozen USB drives with that script on two different machines, never saw any errors or complaints from Defender.

FWIW, I can see why Defender would cast a suspicious eye at the script, it is messing with boot files. I just checked Defender's log on this machine, no actions at all, and I've run it a few times here.

These two commands gave me the missing Option ROM

Admin CMD Pormpt
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Secureboot /v AvailableUpdates /t REG_DWORD /d 0x5944 /f

Admin Powershell
Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"

Source
...
And gave me Event 1808
Not very much commented on but this seems to be the easiest/quickest way to update all the keys (not just the OpROM key) and as well put in place boot files signed with the 2023 certificate and enable use of them, all in two easy commands. All that's left is to revoke the 2011 key if you need that before Microsoft does it for us.

BUT with a somewhat modern system I still think it a good idea to update BIOS (if one's available) to get all the 2023 keys as defaults. That way there's no possibility for problems after doing a CMOS reset or anything else which could revert all the keys to defaults.

I got this new BIOS update notice from Dell this morning that contains the new 2023 Secure Boot Certificates. So, it looks like Dell, at least, is starting to push these certificates out. This update is for my System One, I have not checked for my System Two machine yet.

I have not downloaded and installed this BIOS yet; I normally wait a week after Dell releases a new BIOS before I download and install it.

I got a Bios update for my HP a couple days ago, but I can't find any info on what it contains. Quick googling around try to find in seems the only
thing I can find is HP covers up any info for security so no one can spoof the BIOS into something else.

So I have no idea if the CA's in the BIOS are updated. The BIOS installed was:
HP Inc. Driver Update (15.54.0.0) Device Manager shows date of: 8/15/2025 This update came through WU.

I have the same situation with my HP laptop... no visibility into what updates actually do, not even half way useful release notes.

If it has updated to this new BIOS (probably a good idea regardless) then run the powershell script that looks into BIOS for the secure boot keys and reports on what is found. It works regardless of the method used to put them in the secure boot variables. It linked through the post below.

"as far as I know there hasn't been any further communications from HP on what to do to prepare, other than "update BIOS and hope everything goes well in the future". Compare that with Dell, who has articles specifying what BIOS versions their computers need to be at for compliance."

That's a tough one where you received no information. Somewhere, back in this thread, there is a PowerShell script that when run can tell you about the status of your Secure Boot Certificates. I would point you to it, but I don't know where it is now... this thread is so long. Maybe someone else knows just where it is.

    The Samsung NVMe PM9C1a 1024GB SSD does not use a Phison NAND controller. Instead, it uses Samsung's in-house developed Piccolo (S4LY022) 6-Core 4 Channel Controller. The PM9C1a utilizes a controller built using Samsung's 5-nanometer process and seventh-generation V-NAND technology. 🤔
