A command prompt is a command you issue to your computer using a built-in program. To change a computer password using Microsoft Command Prompt, follow these instructions. 1. Open command prompt: To do this just click or press the windows start button on your pc and type in command prompt...then click the command prompt icon when it shows or hold the windows start button and press R to open the windows run menu then type in cmd to open command prompt 2.To change a user's password at the command prompt, log on as an administrator and type: net user user_name * /domain When you are prompted to type a password for the user, type the new password, not the existing password. After you type the new password, the system prompts you to retype the password to confirm. The password is now changed.

Alternatively, you can type the following command: net user user_name new_password When you do so, the password changes without prompting you again. This command also enables you to change passwords in a batch file.

Non-administrators receive a "System error 5 has occurred. Access is denied" error message when they attempt to change the password
