Change Administrator password with command prompt

Just sharing, For my friends who have forgotten the password on the windows,we can change the password without know the old password with command prompt

Go to Start-Run or Windows + R
then typing 'cmd' or 'command' without quotes.

The next type net user username *
customized on a user name with the username that you want to change the password.

For example:
net user administrator * then enter.

then you will be required to enter a new password, and finish. administrator password can be changed. except when the a command prompt on the disabled ,or windows is in protected . this way can not be in use ..
may be useful:)
