    Mystery SID. Help plz.

    When I find, and then search, an unknown user in my computer, and nothing comes back, I worry.

    Is this defaultuser0, my alter-ego?

    This is me:

    So, who is this defaultuser0?
    Cloudexperiencehost,, which I found in windows10 Firewall, inbound.

    I HAVE FOUND 2 DIFFERENT SID'S FOR defaultuser0!

    I am just learning, so bear with me, but I am on a quest to get to the bottom of ANY user on my computer that I have not authorized: I am tired of changing my settings BACK to the way I set them, and, just maybe, defaultuser0 could be responsible.

    Correct me, if I am wrong, or say "me too".

    I would search the registry (REGEDIT) for that SID for some clue as to what it is.

    Open Command Prompt or PowerShell, enter command wmic useraccount get name,sid. This gives you a detailed list showing which SID belongs to which user account.
