Which command is used to create a new user account in Windows?

The command that is used to create a new user account in Windows is "net user [username] [password] /add." This command is part of the Windows Command Prompt utilities and specifically designed to manage user accounts.

When using this command, "[username]" is replaced with the desired name for the new user account, and "[password]" is specified as the initial password for that account. The "/add" switch tells the system that you want to create a new account. This command is widely supported across various versions of Windows and integrates with the security and user management frameworks that Windows offers.

Other commands listed may be used in different systems or contexts but are not applicable for creating user accounts on Windows. For example, "add user" might resemble syntax used in other operating systems but is not valid in the Windows environment. Similarly, "useradd" is a command typically used in Linux systems rather than Windows. The "create user" command does not exist within the Windows command line context, making it an inappropriate choice for this task. Therefore, the selected command stands out as the correct option for creating new user accounts in a Windows setting.
