I was thinking that you might be be able to use MoveFileEx with 
MOVEFILE_DELAY_UNTIL_REBOOT but that one requires admin rights. Adding
the need for Vista is also not helping much ;-)
I don't know if there is a similar function which can be used by normal
users.

Indeed that would not work in that case.

Option #1
It shouldn't be to hard to keep a list in a txt file (or ini-file) of
temporary files you app created and keep that file in the same
directory.

Next make a little utility that can read that ini-file and delete the
files which are in the list. Remove the file from the list when it was
actual possible to delete the file (some will fail to delete when the
file is still in use by another application).

You could start this utility when your application is closed. That
should take care of most of the temporary files assuming that your app
is used frequently (and closed frequently).

Next thing you also might consider is to start this utility at startup
by creating an entry in the RunOnce as soon as a temporary file is
created. See...
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

The utility should also check and remove that entry when it succeeded
in deleting all files mentioned in the ini-file.


Option #2
You might want to switch from using the standard temporary path to a
directory in of the other user paths (CSIDL_APPDATA for instance) to
store the temporary files. Dump all temporary files in this directory
and just delete all files in it when your application closes.
You can then also again use the RunOnce key to empty the folder at
startup of windows...
  DeleteJunk REG_SZ cmd /C del /q "%APPDATA%\YourAppName\YourTemp\*.*"

I don't know of a way to make that work with the bunch of office
applications you mentioned.
