Windows 10: Disc properties unknown user

Today in my disc properties security tab I found an unknown user with some numbers and letters. I searched it on the internet and apparently it might not be a hacker or malware. What is it though? ShouldI delete it? Also, I don't remember making an account and then deleting it and I use malwarebytes as an antivirus.

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

 

Delete "Account Unknown" from "System Properties" - "User Profiles"?

Please (re)read my original post. Here is a screenshot of my "User Profiles" list to make it clearer:



The list can be accessed on the "Advanced" tab of "Advanced System Settings".
I prefer not to post a screenshot of my registry.

 

Unknown user

<Okänd kontakt> is just Swedish for <Unknown contact>

When an unknown account is listed in permissions it's usually due to the file or folder having had permissions for a user account on this PC that has since been deleted. Or, if the drive is an external drive that is used by several machines, an account that exists on another PC.

Either way, as the unknown user doesn't exist on this PC then having it listed in permissions doesn't grant access to any account that actually exists.
