    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.

    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
    
    
    Get-UEFISecureBootCerts kek | select SignatureSubject
    
    
    

    Certificates which are updated are listed here:

    https://support.microsoft.com/en-us/topic/windows-secure-boot-certificate-expiration-and-ca-updates-7ff40d33-95dc-4c3c-8725-a9b95457578e

    WinCsFlags is going to update ALL FOUR certificates listed. Also the one stored in KEK.

    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.

    If all is updated, you can set back the update configuration:

    WinCsFlags.exe /apply --key "F33E0C8E001"

    STOP!

    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.
