Hi Dave,
If you already have Word, open the .pdf in Word and then save it as a .doc/docx file.
In the past, I have used FormatFactory for the conversion. However, Windows blocks updated versions of that program alleging a virus. In the past, a FormatFactory install offered shovelware unless you declined it. More recent versions apparently attempt to install malicious software.
There are numerous free programs that convert .pdf to Word on line. I don't have a recommendation here.
