Need Free Brute Force Password Recovery

[Captin]

Hey,

My mom has a blocking system and I want to find out the pass so I can go in and out of it as I please.

If anyone know's of a good free Brute Force Password Recovery thing could you give it to me?

I don't want it to have a limit where I can only look for passwords with 3 letters cause I haven't bought it yet. I need to use it fully

Thanks

Brutus works pretty good.. you need WinRAR though.
