Crack Windows passwords with Ophcrack

I try it, Downloaded the Live CD, burn it and boot it with it. It found the user accounts in the system and after about 20 minutes of scanning with the tables it didn't find the password.

It found my password fine. Apparantly if your password is longer than 14 characters then it uses "NThash" to store the password instead of "LMhash" which is much easier to crack.

I have downloaded Windows Password Recovery Tool 3.0 from http://www.windowspasswordsrecovery.com. it not only supports XP, 2000, and NT, I have personally tested it with Vista Home Premium and Ultimate. It works perfectly to reset any local user account to a blank password. I Wrote it to an old 128mb USB flash drive do this. Booting up and clearing a password takes a minute or two works like a charm.

here is the methods I know.

The first thing which you check if you forget login password. When we install Windows, it automatically creates an account "Administrator" and sets its password to blank. So if you have forget Your user account password then try this:
Start system and when you See Windows Welcome screen / Login screen, press ctrl+alt+del keys Twice and it'll show Classic Login box. Now type "Administrator" (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from "Control Panel -> User Accounts".
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

Windows XP and further versions also provide another method to recover forgotten Password by using "Reset Disk". If you created a Password Reset Disk in Past, you can use that disk to reset the password. To know more about It, please visit http://www.resetwindowspassword.com/
