Strange "Unknown" User Account on Security Tab - SOLVED (Sort of)

I happened to look at the Security tab of file properties and noticed a strange "Unknown" user account.

The SID isn't listed in the registry under HKEY_Users and doesn't appear in Control Panel User Accounts.

Should I delete this account? How can I figure out what it is?

 

How to Create MUlti-user Folder Security for a School Setting

Samuria,

Thanks for the suggests. A couple of comments or questions.
1)There is no group called Everyone on my security tab
2)is there a precedence order on the list of Users/groups on the Security tab. For example is it top to bottom or bottom up? Do individual users have precedence to groups
3) is there a defined hierarchy to the list of. For example is Users a subset of Authenticated Users,....

Again, thanks for taking your time to respond

 

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
