Secure Boot certificates have been updated but are not yet applied

Hello,

User's image

What's this? Do I need to take any action about it or just leave it alone?

Thanks very much😀

Hi Wilson T,

Try rebooting your computer, they get installed / replaced on the boot cycle and then recheck your event viewer. FYI I also have the 1801 event error number scatted amongst all the events, so I don't think you have too much to worry about. Let us know after rebooting if you still have 1801 coming up.

It does have an effect... it causes the computer to lag up to 30 seconds....a lifetime if you are trading stocks and options on the platform.

With the optional update from October 28 (KB5067036), Microsoft introduced a CLI tool for the WinCS API. Install https://support.microsoft.com/en-us/topic/windows-configuration-system-wincs-apis-for-secure-boot-d3e64aa0-6095-4f8a-b8e4-fbfda254a8fe

Now install this PowerShell-Module:

Install-Module UEFIv2 -Force

You can list now the certificates:

Get-UEFISecureBootCerts db | select SignatureSubject

Which certificates are needed is listed here:
https://support.microsoft.com/en-us/topic/windows-secure-boot-certificate-expiration-and-ca-updates-7ff40d33-95dc-4c3c-8725-a9b95457578e

Now set the update configuration:

WinCsFlags.exe /apply --key "F33E0C8E002"

Now, run the Scheduled Task Secure-Boot-Update.

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

Reboot twice and check again for the certificates and the Event-Log.

I have a similar kind of issue. I have a Dell 7350 laptop and it keeps restarting every time I shutdown. When I checked the event log, same error is there. Would that be fixed by @John Westfield 's fix?

Hello, Wilson T.

If the OS is stable, you can ignore these messages. Judging by the information from the screenshot, they relate to updates from Lenovo (the manufacturer of your PC).

P.S. Even on a fully functional PC and a working OS, there are always similar messages in the Event Viewer. This is the normal behavior of the log collector.

e.g. DELL will NOT update Optiplex 7050 UEFI (2017) because they let MS do the job.

Hi Gary Rogers,

I dont think Secure Boot certificate would cause an issue as far as 30 second freeze is concerned, what make and model is your computer, the drivers installed, this sounds far more likely to hardware/ software issue. I can help by pointing which logs to look at that might show which part is causing these delays, let me know.

Dell Pro Slim Plus QBS1250, all drivers updated via their website. I uploaded the logs to Dell, but no solution as of yet. Reset to original state and updated Windows 11 to latest patches and updated all drivers yet again. Still no solution to temporary freezes (10 sec. --- I exaggerated when I said 30 seconds because that's what it seemed like at the time).

May not be an issue. Check your BIOS for your type of boot. If you are using the LEGACY boot, then you're not using the secure boot or the these keys anyway and so updating is NOT necessary. Life goes on, albeit with a once per month error in the event log.

DO NOT CHANGE from Legacy Boot to Secure Boot because this will require a reinstall of Windows, and I'm pretty sure you don't want to do that.

Follow the steps under the Device testing using registry keys heading, in the grey box on the linked page. These worked for me also. Before I followed the steps I ran https://github.com/cjee21/Check-UEFISecureBootVariables/blob/main/Check%20Windows%20state.cmd and UEFICA2023Status was InProgress. After UEFICA2023Status was Updated.

Same issue appeared today. I especially like the part where it says "Review the published guidance to complete the update and ensure full protection." Yet, there is no info on the associated link that explains how to perform that cert update process for your typical Home user. Instead, they state that one must be familiar with the entire UEFI specification! MS is so F'd up!

When users use older PC's ( Win7 + )as backup with data on & MS then downloads an update + Edge and user can no longer use PC. This is Cooperative Vandalism, MS knows this will cause problems but doesn't care !!!. With no fix or support shown !.

I have the same problem. Additionally I get TPM rpoblems when installing Win11 25H2 as an inplace upgrade. The upgrade error log says that there is no 2023 certificate found so TPM can't be activated.

Error: 0x8007042B[gle=0x00000002]

this is annoying. No BIOS updates from DELL at the moment.

I cleared my TPM in BIOS, didn'T work.
