Set \pdfminorversion=5 in your documents but don't expect any

If you want to create smaller files, read the pdfTeX manual and look
for "object stream compression".  Simply switching to PDF-1.5 is
absolutely worthless.  You have to enable the features provided by the
PDF-1.5 spec explicitly.  I tried "object stream compression" already
and came to the conclusion that compressing these tiny things isn't
worth the effort at all.  You only save a few bytes but your PDF file
is incompatible with older versions of Adobe Reader then.

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