Windows 10: How to remove unknown user on laptop

We have just purchased a new windows laptop but when trying to set up our profile we have noticed there is a username already on the laptop. How do we remove this user? Thanks

:)

 

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

 

Removing a "hidden" user and user files

Thanks for your patience. I was able with "Net User" to remove the left over user. It no longer appears when I invoke Net User.

Now for the user's folder which remains behind. After performing the series of steps that you suggested, I attempted to delete this folder. The result again was an error message about permission


"Administrators" appears on the list in the list of advanced security.

 

Unknown User - Powershell context menu - unable to remove permissions

Running Windows 10 - poweshell.exe loads on startup (context menu).

I am unable to remove it. There is an unknown user (see screen shot)

that I can not remove from permissions. When I remove it, the unknown user reappears when I apply changes. I am the only user listed on the PC, I am unable to see "any other" users listed. I have full Admin user rights.

I am trying to remove powershell from the computer but it keep reinstalling itself I once was able to delete all references to powershell, but it reinstalled as part of an update.

After taking ownership and changing access rights on folders the files and registry entries to full access, they still cannot be deleted?

I understand powershell is not needed in windows 10, but it may allow other users to remotely access my system?

why does this unknown user auto give itself permissions after being removed?
