Word
can store personal
document templates in one of two locations - User Templates and Workgroup Templates, the locations of which are defined in
tools > options > file locations (see
illustration below, where the default location has been changed to a
folder on my data drive).
Additionally Word will *load* automatically any template or add-in in the Word startup folder or the Office startup folder. The former is defined in file locations, the latter will be at
\Program Files\Microsoft Office\Office11\Startup.
11 here is the location for files for
Office 11 i.e. Office 2003. For Office 2002 this would be Office 10, and
for Office 2000 just Office on its own.
This can cause some confusion after upgrading, when
add-ins using that folder (e.g. Adobe Acrobat) no longer appear to work.
Word simply no longer sees the add-ins in the startup folder of the
earlier version. Allowing Word's setup routine to perform the upgrade
should cause the add-ins to be moved, but if add-ins fail to load after
an upgrade this is the first place to look.

By pointing their versions of Word
to the same Workgroup and Startup folders
you can make document templates and add-ins available to users
on a network.
