The Administrator is a user, while the administrators is a user group (the "user" cannot be created on the computer if it is not a user ). Since it is a group, it is necessary to have members. By default, the former is a member of the latter. Of course, you can continue to add members. Members in the same user group have the same permissions. Therefore, after you create an ABC user and add it to the group, ABC is a system administrator, non-family systems can use lusrmgr. MSC to manage the relationship between users and groups. In addition, the Administrator and administrators of the original system can modify the name but cannot be deleted.
