Yes, exactly what you say, that's what I thought too.
The first 2 steps in my believing should be enough, but I'm going to do the last step anyway.
The only reason I'm asking this is because I want to make sure I can do the last step so (Set-SmbServerConfiguration -EnableSMB1Protocol $false) without any risk.
So assuming that the first 2 steps have been performed and so the feature is disabled, this should mean that SMBv1 is no longer used.
So when I perform the last step, I actually want to be sure (provided that the feature is disabled) whether this has no consequences that SMB1 is used in one way or another or something like that if you understand what I mean.
