How can I set up something that automatically converts my files so that any
receipent will be able to view my Microsoft Word files from my operating
system which is Vista?
The fact that you are using Vista is irrelevant. The operating system
doesn't matter. In order for any recipient to be able to read your
document, you need to save it in a format that their software can
read.
The most generally compatible format is a plain text (.txt) file, but
that doesn't permit any formatting. The next more generally compatible
is rich text format. If you save your file as an .rtf file, much of
the formatting will be preserved, and almost everyone will be able to
view it.
The most flexible format is Adobe's pdf format. Depending on what
version of Word you have, you may be able to create pdf files, or if
not, you can get a free or inexpensive pdf creation program like
pdf995. A pdf file should preserve all your formatting, and most
people have a pdf reader program installed, whether Adobe Reader or
some alternative.
