Change administrator name ?

Good evening,
I have installed 2 new laptops and it went fine ... until my wife insisted having the other one.
So I had to swap all accounts, from windows, msoft and mozilla.
This took a whole day s work but I am not sure it is OK.
I just can't let it record the administrator is me and not anymore my wife.
It constantly points to the other msoft account, a real mess !
How do I do this swap properly?
Thanks a lot !
W11 home on both pcs. Updated to the brim.

You are not very clear of what kind of account you are using (Microsoft or Local) user account.

Good morning
Thanks a lot ! I could do it, with the netplz command.
It was a little more complicated but I was successfull in the end. However, all updates have to be reloaded again. Not a big deal.
Thanks for your help !
Hve a good day and in advance, I wish you a very happy new year !
