Windows 10: Authorized Users of Laptop

My 13yo inserted himself as the administrator user on my new laptop. How do I change administrator user to me? How do I remove my son as a user and block him from logging in on my laptop?

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.

 

Best laptop under $800??

Well the last one I suggested seems to be the best for 650$

NT AUTHORITY\Authenticated Users added to Users group upon every restart

I have a Windows 10 computer that I would only like certain users on a domain to be able to login to. Lets say limit access to only those users in the group named football.

I have added the football group to the Windows users group. The computer is on a domain and I noticed the following two groups both of which I removed from the Windows users group.

• NT AUTHORITY\Authenticated Users
• NT AUTHORITY\Interactive

I have tested that NT AUTHORITY\Authenticated Users is allowing users outside of the football group to login to the computer and this is not wanted.

If I remove both of these groups from the Windows users group then they will reappear upon every restart of the computer. This did not have with Windows 7. This seems to be a security problem???
