Read the end of the post for the source. And please, I'm no scriptkiddie. (and I pretty much consider that a derogatory term) I've been a part-time sysadmin and I know the problems that can arise when a certified genius manages to lose his Administrator password as well as forget his usual account login password.
Like I said, its for legit users to save themselves a lot of time reinstalling and restoring the computer to its normal working status. And just for the record,
I DO NOT go around using these tools to reset every other admin password I see. I AM NOT A SCRIPTKIDDIE.
