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 hash function.

What is hash and how it works?
After stealing hash, convert this hash to 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 than copy hash file directly from the above shown paths and convert these hashes to desired password for this conversion many software are present , one of which is rainbowcrack.

If you want to secretly steal password than it is up to you than how can you implement this technique from network.

But all this is not so simple so below is the more easy method by using graphical user interface.
