How to Recover Passwords Using Ophcrack LiveCD

1. Download Ophcrack LiveCD
2. Burn to a CD
3.Boot from Ophcrack LiveCD
4. Ophcrack will attempt to recover the passwords for all of the user accounts that it can find on your computer. This password cracking process is completely automated. The important things to look for here are the accounts listed in the User column and the passwords listed in the NT Pwd column. If the user account you're looking for isn't listed, Ophcrack didn't find that user on your computer. If the NT Pwd field is blank for a particular user, the password has not been recovered yet.
As you can see in the example above, the passwords for the Administrator and Guest accounts are listed as empty. If you were cracking a password for a user that Ophcrack shows as empty, you now know that you can log on to the account without a password at all, assuming that the user account is enabled.
Look toward the bottom of the user list - see the Tim user account? In under one minute, Ophcrack recovered the password to this account - applesauce. You can ignore any other accounts you're not interested in recovering the passwords for.
After Ophcrack recovers your password, write it down, remove the Ophcrack LiveCD disc from your optical drive and restart your computer. You don't need to exit the Ophcrack software - it won't harm your computer to power it off or restart it while it's running.
In the next step, you'll finally get to log on to Windows with your new password!
Note: If you do not remove the Ophcrack LiveCD disc before you restart, your computer will likely boot from the Ophcrack disc instead of your hard drive.
. ow that your password has been recovered using Ophcrack LiveCD, simply enter your password when prompted after booting your computer normally.
To avoid needing to hack your own password again someday, I recommend creating a password reset disk. As long as you can keep the disk safe and also avoid losing it, you'll be protected from any future forgetfulness when it comes to your Windows password:

master password


Call the manufacturer they may be able to help you get past that. If not, at worse, you'll have to reboot it. To do that, as it is booting continuously press the F10 key (it may be a different key on your model) then follow the onscreen instructions.
There are also some programs you can boot from a flash drive that will help hack your own computer.

I lost my password my screen is locked how can I reset or bypass?


This is about topic bypass Windows logon screen. Command Prompt or recovery utility is effective ways for reset or bypass lost Windows password.

First, run command prompt with administrator. And you can reset Windows lost password with this command. Net user <new user> <new password>

Second, take recovery utility to burn a password reset disk. And this reset disk is the key to remove or reset Windows password, applied for standard or admin account. When your computer is installed with Windows 8/7/Vista, forgotten user password would be removed. If it is Windows server 2012/2008 etc, password would be reset as "iSunshare@2012".

I have an IBM thinkpad x41 and it comes to the Windows xp screen needing a password and I dont know the password can someone help me?


You can use Ophcrack, an open source software. You don't need any access to Windows to be able to recover your lost passwords. Simply visit the site, download the free ISO image, burn it to a CD and boot from the CD. The Ophcrack program starts, locates the Windows user accounts, and proceeds to recover (crack) the passwords - all automatically.

Here is the link to download you ISO file to burn to a cd.
http://downloads.sourceforge.net/ophcrack/ophcrack-xp-livecd-2.3.1.iso

Or use Another computer by installing the exe file and make a cd for your recovery:
http://downloads.sourceforge.net/ophcrack/ophcrack-win32-installer-3.3.1.exe
