To obtain the password to your Windows 7 account, use the OphCrack Live ISO file. Obtain a CD or a USB flash drive and download the ISO from the official website. Use your favorite burning application to burn the ISO file as BOOTABLE to CD or use UNetbootin to write the ISO file to the USB drive. Restart the computer, boot from CD or USB and wait for the OS to load. The password will be displayed on screen after it's found.
