ADDUSERS is a command-line utility in Windows that enables the batch creation, modification, or deletion of user accounts. It can also export existing account profiles. This command is particularly useful in large organizations or network environments where managing multiple user accounts efficiently is required.


The ADDUSERS command has different syntax depending on its intended function, whether adding, deleting, or exporting users:

ADDUSERS [/s:x /d{:u | :c} [{/f:filename | /p:{l | c | e | d}}]] [/c:filename]
  • /s:x – Specifies the character used as a delimiter in the CSV file (default is ,).
  • /d – Directive to add users. The option can be :u to create users, :c to create users and add them to groups.
  • /f:filename – Specifies the CSV file used for user account operations.
  • /p:x – Sets the password requirements where l is for blank passwords, c for user must change password, e for password never expires, and d for disabled account.
  • /c:filename – Used for exporting users; specifies the CSV file to which user profiles should be exported.


  • /s:x – Changes the default delimiter in CSV files, allowing flexibility with file formats.
  • /d – Determines the mode of operation for adding users with variations for user creation and group additions.
  • /f:filename – Indicates the file from which to read or write user data. Essential for batch operations.
  • /p:x – Configures password properties, critical for security and compliance with organizational policies.
  • /c:filename – Specifies the output file when exporting user data, useful for backups or migrations.


1. Adding Users:
To add users from a CSV file named users.csv where the user must change the password at the next logon:

ADDUSERS /d /f:users.csv /p:c

2. Exporting User Accounts:
Export current user accounts into a file named export.csv:

ADDUSERS /c:export.csv

Common Issues

  • File Format Errors: If the CSV file is not correctly formatted, ADDUSERS might fail to parse it. Ensure the CSV adheres to the expected structure with appropriate headings and delimiters.
  • Permission Issues: Running ADDUSERS without sufficient permissions can lead to failures. Ensure it’s run with administrative privileges.


Integrate ADDUSERS with other commands for powerful scripting. Example with FOR loop to process multiple files:

FOR %f IN (users1.csv, users2.csv) DO ADDUSERS /d /f:%f /p:e

This script processes multiple CSV files, adding users with passwords set to never expire.

  • NET USER: Allows detailed management of user accounts directly.
  • WMIC: Interface for system management including user accounts.
