The program seemed promising, as I first installed it on my computer to check it out. The problem is that I can't install a program on my parents' computer because I need be "logged on as an administrator to install the program".
So, I'm back to where I started.
I think there's something on that page about making a Linux boot disc. You'd boot to Linux from your CD-ROM instead of loading Windows. Then you run this simple program, choose a new password and you're in. I don't know the first thing about Linux but I remember this being really quick and simple.
If that page doesn't have it just google around some more, "linux boot disk windows password" is one of google's predicted searches as you're typing so it should be pretty easy to find.
