    Microsoft guidance for applying Secure Boot DBX update (ADV 200011) does not work.

    Microsoft guidance for applying Secure Boot DBX update (ADV 200011) does not work.

    Source: Microsoft guidance for applying Secure Boot DBX update

    The description under step 3 seems to be incorrect:

    Set-SecureBootUefi -Name dbx -ContentFilePath .\content.bin -SignedFilePath .\signature.p7 -Time 2010-03-06T19:17:21Z -AppendWrite'

    It also does not describe how to determine again whether the problem has been fixed. When I re-check the changes using the following CmdLet, I always get a "true" result.

    [System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match 'Microsoft Corporation UEFI CA 2011'

    Is the CommandLet in step 3 only an example? Which time stamp (-Time) do I have to use?

    Steps 1-2 worked correctly.

    Best regards
