I misjudged you.  I thought you were new to this and missed that what you 
were new to was the vagarities of Windows and of C++.

Yes.  Windows.h actually does a number of includes itself.  By including 
that file you get many typedefs, macros and structure definitions as well as 
the function prototypes for what Windows provides.

Note that if you are writing a VCL based program (most of what I do is not 
VCL), you probably don't need to include windows.h because vcl.h provides 
what you need.

There is one additional thing you need to know.  Long ago Microsoft did not 
support C++ so did Windows headers for old-timey C (K&R 1, pre-ANSI standard 
C).  These days functions prototypes are checked against use of those 
functions for proper argument lists.  If you get an error on the EnumProc 
argument of EnumWindows then either put this as the first line in the file

#define STRICT

or define it under Options|Project defines.  STRICT is Microsoft's 
workaround to alter the expansion of windows.h to support the "new" way 
stuff has been done (since the late 80's! ).
