  1. Unknown User Account


    Hi, I want to get rid of an Unknown User Account and I don't know how to do it safely.

    The standard method doesn't apply because I can't see my Unknown User Account in Control Panel --> User Accounts. Matter of fact no matter where I look C:\Users, usrmgr.msc, netplwiz, Windows Settings --> Accounts this Unknown User Account is nowhere to be seen, yet when I use regedit and open a random Properties menu I notice an Unknown User Account there. I tried to delete it, but it automatically adds itself again. See screenshot:

    Above you see the Unknown User Account, and below I'll post several screenshots of other locations on my PC where you don't see it. I'm using a Dutch version, and Openbaar means Public, in case anyone wonders.

    You see, I wasn't kidding when I said that this mysterious Unknown User Account is nowhere to be seen, except of course in Regedit --> Properties of a random key or name.

    To be clear I only have a few Accounts.
    An Administrator Account, which is also my Microsoft Account, and I activated the Build-in Administrator Account:
    net user administrator /active:yes

    I've checked if it was possible to see this Unknown Account if I logged into my Build-in Administrator Account: but the answer is the same as when I'm logged in my Administrator Account I use daily. There was no difference!

    So the mystery is still alive, where is this elusive Unknown User Account located, and how do I delete it?

    PS I've read at least 10 different websites/forums today but none have an answer for my specific problem.
    Hopefully someone is knowledgeable enough here to help me...

    Regards Carlo

    :)

    Unknown User Account created after upgrading to windows 10. It comes back if I delete it.

    Original Title: Unknown User Account

    Hello,

    Since I upgraded to Windows 10 I am seeing an account that I did NOT create. So I deleted it by going into Control Panel > All Control Panel Items > User Accounts > Manage Accounts then I click on the unknown user account and delete it. That said.... It
    comes back. I have also followed the below suggestions from other posts and still does not seem to work.

    Let’s try simple steps and check if the user account is detecting and try removing it.

    • Press Windows key + R, type netplwiz and press Enter.

    • Check if the user account is appearing on the list.

    • Click on user account and click on Remove. (If user account appear on the list).
    Please advise.

    Thank you

  4. Unknown User Account

    Unknown second user account


    I took the free upgrade to Windows 10 about a week ago. An unknown second user has started appearing on the password log-in screen. It has the name 'smmosbvjntf'. It is easily removed from the user account box but usually reappears on the log-in screen within 24 hours.

    I also get a pop up from Tweakbit which wants me to use it to clean up my computer. I'm ignoring that.

    I subscribe to Eset and have scanned my laptop several timesusing the Eset scan and have come out with a completely clean bill of health.

    Any suggestions of how to rid myself completely of this unknown second account user?
