WINDOWS.H already included. MFC apps must not #include <windows.h>

I am making the dll out of an exe. I know that this error goes out when u adjust the order of your includes. I want to know the actual cause of this error and what we have to consider in order to get rid of it.

Error 2 fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h> C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include\afxv_w32.h 16

What order do you have your includes in?

Have you tried not including <windows.h> like it says?
