How To Get System Files Size Down

today i deleted the dirctory "servicepackagefiles" in directory "WINDOWS"

and NOTHING happened. So i think we maybe never use some of funtions in windows , and the files of those can be deleted even when they are in system files.

The question is which files and functions we don't need.

Plz give your suggestion
