Cracking Windows Password using ophcrack

If you have forgotten your Windows password or you want to hack any accountant system or for any reason, you want to hack Windows than this is possible by stealing stored hashes in windows. Password created for windows or for any type of security gateway is never stored in its textual form it is always converted to its hash using the hash function.

After stealing hash, convert this hash to a password.

Where is your hash? 

1)In the folder C:\windows\system32\config. This folder is locked to all accounts (including an Administrator account) while running, except the special System account.

2)In a SAM file from C:\windows\repair if rdisk has ever run

3)In the registry, under HKEY_LOCAL_MACHINESAM, which is locked to all accounts

Now these hashes cannot directly be used as because of windows file protection system so how can you hack them, here is the way
Boot to any Linux OS then copy the hash file directly from the above-shown paths and convert these hashes to the desired password for this conversion many software are present, one of which is rainbow crack.
If you want to secretly steal password than it is up to you then how can you implement this technique from a network?
But all this is not so simple so below is the more easy method by using graphical user interface.  

Here comes the Ophcrack.

Ophcrack is a free Windows password cracker which can crack almost every password. It comes with an easy Graphical User Interface so you don’t have to mess with Unix terminal for hacking. 
Ophcrack is a software that can be installed directly to victim windows or you can use a Live CD if you cannot boot to windows. Ophcrack uses rainbow table for cracking hashes. 

* It runs on every platform.
*  It can crack LM and NTLM hashes.
* Free and open source software (GPL).
* Brute-force module for simple passwords.

Also if you use direct installation it requires you to download rainbow tables separately but in LIVE CD it is built-in.
