How to Hack or Crack window Admins Password

Hey Friends, Today we are going to learn a different way to hack admin password in windows xp using Backtrack ,a linux variant .

This tutorial is for the newbies and noobs and I have made everything clear and easily understandable .This trick works 100% on all PC's ,Laptops, Servers. Basically , We know that Microsoft windows xp stores all the passwords in SAM file located in Windows directory.

What we are going to do is getting that file to crack the password.We are using Backtrack to copy the sam file , because the sam file and folder is inaccessible through windows explorer.

So, Backtrack is used for this as, it has raw access to hard disk content. Now we have the sam file so, we will use some tools to get password from sam file.

So , here goes the tutorial ,
>>> Requirements: BackTrack Linux 4 or 5.
Download it from One pen drive(above 4gb)
