Cracking a Windows Password

When most of the people in my life have a computer problem, they come to me, naturally. Not often does it include a hacking challenge. Not that I condone hacking into someone else's computer, but in this case it was necessary. Someone passed away unexpectedly and the family needed access to her computer. I had never cracked a Windows password. Bios, sure - just remove the battery. But Windows - hmmm. I knew there were some programs out there made for this, but didn't know how well any of them would work. Ophcrack seemed the best from what I read around the web. I downloaded & burned the live cd, set a password for my XP system and fired it up. In less than 2 minutes it had cracked my password. Hmm, lets set a longer password and try again... same result. Sweet!
