On Windows both, TeX Live and MikTeX, provide a hidden Ghostscript
which is used by programs which are part of these distributions.  On
all other platforms it's assumed that Ghostscript exists on the system
already. 

TeX Live also provides a hidden Perl in order to run epstopdf while in
MikTeX the script was ported to C++ and no Perl is required.

BTW, if there is no Ghostscript, where do the PDF files come from?

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
