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
