The built-in System administrator account Administrator is a member of the local group and cannot be removed from the group.
If this computer is joined to a domain, Domain Admins of the domains are automatically added to the computer's Administrators group. In other words, the system administrator on the domain also has the privileges of the system administrator on this machine.
Backup OPerators
Members within the group, whether or not they have access to folders or files on this computer, can back up and restore these folders and files through the start-All Programs-attachments-System Tools-backup path.
Guests
This group is available to users who do not have a user account but need access to resources within the local computer, and members of that group cannot permanently change the working environment of their desktops. The most common default member of this group is User account guest.
Network Configuration Operators
Users within this group can perform general network setup tasks on the client, such as changing the IP address, but cannot install/remove drivers and services, or perform tasks related to network server settings, such as DNS servers, DHCP server settings.
Power Users
Users within this group have more rights than the Users group, but have less rights than the Administrators group, for example, you can:
Create, delete, and change local user accounts
Create, delete, and manage shared folders and shared printers within the local computer
Customize system settings, such as changing the computer time, shutting down the computer, and so on
However, you cannot change administrators and backup Operators, take ownership of files, cannot back up and restore files, cannot install delete and remove device drivers, and cannot manage security and audit logs.

2. Built-in special group:
Everone
Any one user belongs to this group. Note that if the Guest account is enabled, you must be careful when assigning permissions to the Everone group, because when a user without an account connects to the computer, he is allowed to automatically connect with the Guest account, but because guest is also part of the Everone group, So he will have the privileges that everyone has.
