First of all, I would recomend you to learn Assembly language. Once you know assembly, you can pick any debugger you like (i.e. Soft-ICE) to study the code. As far as I know, EXE to C decompilers are very inacurrate, unless you ask it to produce Assembly code packets, inserted in certain functions of your output code. (VrAx)
