My brothers Microsoft account was accessed by some unknown user overnight, and the email/password was either changed or deleted. He can't recover it through Microsoft account recovery because it says, "The Microsoft account you've entered does not exist".What is there that he can do at this point to recover the account? There was a big Xbox game collection and other stuff on that account, and he wouldn't want to lose the account.

Unknown User Account

Hi Brink, thanks for stepping in *Wink

"Account Unknown" is from a user account that had previously accessed the item, and the account is no longer currently available. For example, the account was deleted, or accessed by a user from another computer/network."

As far as I know there hasn't been another Account on my machine, nor accessed from other computers or network.
Because I'm the only user. Could it not due to a major update of Windows? Some other folks allude to that on other forums...

Whatever the cause I'll try your method now and see how far I get...
I'll keep you posted *Wink

 

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
