5. Sit back while ophcrack looks for your password hash in the available tables

I recommend you archive your burned disc for use in the future. Also, consider using a more difficult password to crack and then creating a password reset disk.

If the password is not found, you have a few options:

  1. Access the files using a Linux distribution without cracking the password
  2. Reset the Windows account password to gain access to the account (but lose access to any encrypted files)
  3. If it’s really important that you crack the password, you can purchase larger rainbow tables (link) although there are no guarantees you’ll find a match for your password

    Ophcrack only works on newer systems. A few months ago, I found a couple of desktop computers set out on the curb as trash and on a hunch I grabbed them and brought them home. Both were password protected. One has even the SAFEmode admin account sealed with a password so I can’t use the little bypass which worked on the other one mentioned in the article. I learned about Ophcrack and after much wasted discs, finally successfully made an ISO Image disc…which – according to the folks at Ophcrack themselves! – won’t work in the older system (Pentium 2 600mhz processor). So I STILL haven’t accessed that system. The one I successfully opened is now in use in my studio as a dedicated virtual Minimoog. I uninstalled everything but the OS and soundcard drivers. Works just fine.
