You may wonder why you have two DLL's for each
modular component - the answer is simple. All the DLL's ending with 32 (i.e.
KERNEL32.DLL) are the newer
32-bit Windows DLL's, and the ones not ending in 32 (i.e.
KERNEL.DLL) are the older
Windows 3.11 DLL's that make up the
16-bit virtual sand-box in all the 32-bit Windows environments.
The modular approach is virtually unchanged since
Windows 3.0 (or 3.1,
correct me if I'm wrong).
