Best Free PDF Utility for Windows ... Again?

[Lou Quillio]

I don't usually mess with Windows, but sometimes I have to.

Right now I'm dumping out a Word doc to PDF using the utility I
found already installed, RoboPDF.

Nice job, bookmarks, thumbnails, all that.  But it's not handling
_some_ text in _some_ embedded Visio objects in this inherited doc.
 Black background on the text, like MI6 redacted it.

So, you know, we've seen this before.  Off I go to find other MS
Office-aware PDF utils and, sure enough, some of them don't have
this issue and others do.

Save me some time.  What's the best, free, Office-aware PDF
conversion utility for Windows these days?  Preferably one that
isn't up-selling to "Pro", etc.  Free as in beer *and* speech.

(Somebody made a sound recommendation here recently, but I can't
locate it now.  "PDF" is took common a term here.)
