Office File Validation
The KB2501584 Office File Validation add-in works with Office 2003, 2007 and 2010. Architecture updates need to be applied to Office 2003 and 2007 (see the KB article), but Microsoft Update should be able to download them on its own. Office File Validation requires a license agreement to be accepted, so Microsoft Update won't install it non-interactively.

<!-- change this if switching to Office 2010 -->
<!-- this also depends on KB2464605 and KB2464599, which, as far as I know,
will be automatically installed by Microsoft Update. OFV won't be
automatically installed because it requires a license be accepted. -->
