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.

With some BIOS version like my Dell Optiplex 7050 you first have to empty your certificate memory in your BIOS. Do NOT user Factory Settings => USe DELETE ALL! With this EMPTY certificate memory you can boot your machine in SETUP MODE and Windows will write the new certificates in your BIOS Memory. If it doesn't, use Garlin UEFI Tool from GitHub. I managed to update my machine to the new certs and I'm happy now. btw, the option to delete the certificates in BIOS may only be visible in "Custom Mode" NOT "Standard Mode". Some machines like Acer Aspire even need you to setup a BIOS password to get into Secure Boot Custom Mode and to DELETE ALL certificates. Use an easy password and delete it immed afterwards. All the best to you

Great to hear you fixed your system. The problem for everyone I think is that MS Downloads an update regardless. My Backup system on Network is a Win7 Pro X64 with EUFI yet this got a download + Edge, not asked for or wanted. These systems are supposed to be not supported. I made mistake of going on MS site for some info & Zap. The system got this download. After S/W off, PC would not restart, regardless of all the items to try, nothing works !. Now have to recover DOCs and Pics with Ubuntu ! A right pain, must be causing problems for millions, no doubt MS hoping that lots of folk will buy NEW PC's & Win11 ! I think this is a Marketing Ploy. Rgds.
