How can I set "Final" as the default selection instead of "Final showing markup" in Word 2007's review section?

"From Track changes in Word 2007

There is a way, but first let me tell
you why you shouldn't use it. By
default the document opens in Final
Showing Markup whenever there is
markup that hasn't been accepted, to
protect you from sending the document
to another computer without realizing
the markup is there. There have been
some very embarrassing and very public
instances of that among corporate and
government users.

If you insist: Go to Office button >
Word Options > Trust Center > Trust
Center Settings > Privacy Options. In
the Document-specific section, clear
the checkbox for ""Make hidden markup
visible when opening or saving"". Just
remember that it's now up to you to
look for markup before you send the
document to anyone else.

You can also have a look at Turn off/stop/disable Final Showing Markup view in Word, where a macro is supplied:

This macro will make MS Word start up in ""Final"" as opposed to ""Final
Showing Markup."" It's quite annoying when Final Showing Markup is the
default view--this has to stop/be disabled; I hope that this is
addressed in the next version of Office. Back to the point, this macro
will take you back to the days of Word XP and stop the Final Showing
Markup view before it rears its ugly head."
