Thanks for the feedback Ben, but I gave up on this advice. As far as I could
see, Office 2007 does not come with a support.dot template file.
I did a Google search and came up with lots of advice about backing up
autocorrection entries - but most of these were for earlier versions of Word
and many did not even specificy the version that they referred to. Very
unhelpful. None of them worked for me.
However, I did discover that your autocorrection entries are stored in the
normal template (normal.dot). So I did a search for this file with the
intention of locating and copying it. My search failed. The file is hidden.
I eventually found it by enabling the viewing of hidden files and
re-searching.
Normal.dot (in Word 2007 systems running Vista) is stored here:
c:\users\<username>\appdata\roaming\microsoft\templates
Copy this file to your backup device and then copy it back once you have
re-installed your system.
See? Easy! Not.
