Messed with dlls' and fogot... Please Help

OpenGL OpenGL: Basic Coding
1

I have written a few OpenGL programs that I want to upload to a friend.
The problem is that I have messed around such much with my OS’ Windows 2000 and Windows Me that I have forgotten which .dlls
are shipped with these OS and what directories they belong in.
Specifically I need to know what folder they belong in ( system or system32 )when they are shipped from M$, and if glu and glu32.dll
are shipped with the OS to begin with.

opengl.dll
opengl32.dll
glu32.dll
glu.dll

opengl32.dll and glu32.dll is from Microsoft and the other is from SGI. I think you only need to have them somewhere in your PATH. If I remember correct is they in the system dir from the beginning.
