Change password xp

First in order to view all user accounts even hidden ones.

1. Start > Run> cmd
2. Within "cmd" type "net users" then hit enter
this will display a list of all user names

Now you know the username of the account whose password you want to change

Now to change the password without knowing the current password

1. Log onto the computer with an account that has administrative rights
2. Start > Run > cmd
3. Within "cmd" enter the command "net user %username% *"

where it says %username% enter the username whose password you want to change. If the username has a space in it for example like "John Doe" place "" arount it. So the command for a username with a space in it would be C:\net user "John Doe" *

4. It should now ask you to type a new password for the user. Be careful of what you type however as the password as you type it will not be displayed.
