Windows 10: Removing the primary User and adding another

I bought my wife a new notebook and I am configuring her previous system. I want to remove her User name and all associated data, and add my name as the primary User. I cannot just do a rename, for that does not work. How do I do this properly?

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.

 

Remove account


I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:
   
   Code:

   net user test /del
