Changing of Windows 7 User Password using Command prompt Without knowing old password

After Logging into the system, a user have two ways to change the password and one method is well know by User Accounts in Control pannel and another by CMD.
            To set the new password to the user we must know the old password of the user account.
But here in this tutorial we change the password of the user without knowing the old password,
as follows in four steps

STEP I :

Hit the windows button  and TYPE the Keyword "CMD" and

Right click on the cmd and click on the RUN as Administrator option

STEP II:

A command prompt opens and type the following command to see the users of the system

>net user

 

STEP III:

Now select the user name you need to change the password and type following command

>net user "USERNAME" <space> *

i.e

>net user a *

 

STEP IV :

Now change the password. Note that you cannot see what you are typing in the prompt(so take care a bit)and thus you can change password with a message "password changed successfully"
