Change user password without knowing password

To change an account password:

1) While logged onto the computer to an account that has administrative rights, click on Start>Run>and type in CMD.

2) Type in net user then the name of the account then * and press enter. here’s an example: net user administrator * or net user "Joe Smith" * . Put the name in quotes if it contains spaces.

3) From there it should ask for a new password. Type in your new password (type very carefully - the command window won't display what you type) and once more to confirm it. If you get the message that the command succeeded successfully you're all set!!
