Most of the passwords in a windoze machine are stored in a .pwl file, which is encripted, there are programs around to decript it quite well.
Now, the hotmail and yahoo passwords? those are not there, and they are not encripted directly, the little **** you see is just to cover the letters from someone looking over your shoulder, the real encription might never take place, or, in the case of hotmail and yahoo, what's encripted is the browser session, using a https:// .
Anyway, your best bet is the cookies folder, so, start fishing and good luck.
