This trick enables us to change the password of  Windows Operating system Using Ubuntu 9.10 distribution installed on a usb drive.   Eventhough the titile states on XP, Vista and 7, the trick you are gonna read is also for 2000 and 2003. This method is applicable when you have some Alzheimer’s disease and you forgot your most important Windows login password.  And probably you do some idiotic things with all the password possibilities you know and then your account gets locked up. So there when you stand without knowing what to do, this trick comes to the rescue.
What do you need :
•    Unetbootin
•    Ubuntu 9.10 ISO (You can also download it using Unetbootin)
•    chntpw
•    A Usb drive (1 gb or more)
Steps :
First we need to install Ubuntu 9.10 to the USB drive..  Open Unetbootin in a computer other than the target computer (you couldn’t do it on the target computer as it is already locked or forgotten password)
