While searching for a win32 port of GNU 'patch' , I came across this great sourceforge page . Although I already have most of important tools ported to win32 , but this package seems clean and complete enough , for most users . This Emacs win32 port looks cool too , if you don`t like any of windows based text editors .
I found this this project to be more decent than the one I've described above. update your bags :)
