You could see all user accounts using Command Prompt:
- Open a Command Prompt window as administrator.
- Type in the command: net user, and then press Enter key so that it will display all user accounts existing on your Windows 10, including the disabled and hidden user accounts. They are arranged from left to right, top to down.
- If you want to view detailed information or properties about a specific user account, just type in the command: net user username, for example, net user Bella, and press Enter key. Then the window displays detailed information and properties about that user account, such as its full name, account active state, if the password is required or not, and so on.
