I believe the original version of gx.dll is actually in ROM. When an application provides a "replacement" it puts the new version in /windows or some known location where the operating system finds it. When gx.dll is called, the default search path is to look in /windows, then the ROM for the file. That pathing mechanism lets MS, or anybody else, for that matter, update some software parts without having to re-flash the ROM. All they have to do is put a file of the same name in /windows and it will be found before the ROM version. MS has updated some files a couple of times in the past using this approach.
