who knows a PGN utility for analyzing

Hello

On this site i've played a lot of chess games.
You can download all your own games as an archive.

Now what i wonder is there some software that could analyze my archived games (which are all in one PGN), and sort them.
Sort by opening and then how often i won such games with it ?.

I've played so many types of openings and i would like to know at which i'm pretty good and at wich i am not that good. For example i think i loose to often with caro kann, but i'm not sure about this; and i also have ideas about it, when to play it and when not to play it.. but maybe i'm better in variation X or Y.

(í'm looking for somehting that runs on windows)
