TechChaser1 has done a nice video about Recovering a Windows Password with Rescatux . He insists that tool is legal and guaranteed (not sure about this last bit ). The great thing about the video is that he is recording an actual computer with a camera, he does no cuts and he explains himself what steps he performs.
Sometimes the screen is a little blurred but the video is more funny than my current Rescatux videos for 0.2X version.
Enjoy the video:
