Groups command failing me in Windows 10

[David]

Hello,

The groups command in the cmd window on Windows 10 shows None as my first group.
When I use the dir command to create a file, the security display shows no error.
When I use the touch command to create a file, I get "The permissions on ... are incorrectly ordered [NULL if first]
I bought two refurbished Windows 10 machines and this is the same on both.
I am on local machines with no outside domain connection.
In the fewest steps, how do I assign this user to a group?
What group should I assign the user to - so that when I create a file the group is set.
Can I do that with net localgroup newgroup Admin /Add
I have been working on this for a couple of weeks and cannot figure it out by myself
and I can't find a wonder answer on google. I am going to take a chance that my
email will be spammed because I really would like to know the answer to this.
So, I have added bcc to myself hoping you can forward to me or answer to me.
