Windows 10: I found two unknown user on my pc

I am using Windows 11 Home Single Language and I have installed Ubuntu on VMware workstation. I recently found two unknown users named Account UnknownS-1-5-21-1817899009-3090463667-2689442307 and Account UnknownS-1-5-21-1817899009-3090463667-2689442307-1001 on my laptop. Do these two unknown users mean that my PC is hacked or it is there because of the Ubuntu in VMware?

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.

 

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

 

Current active users that are friends

The other reason I suggested this is that users can add characters to their username that are not alphanumeric (e.g. user*). This confuses things somewhat when looking at the list.
