Adding

Creating a template
Templates and add-ins can be loaded either for the current session only or whenever you start Word.

On the Tools menu, click Templates and Add-Ins.

Under Global templates and add-ins, select the check box next to the template or add-in you want to load.
If the template or add-in you want does not appear in the box, click Add, switch to the folder that contains the template or add-in you want, click it, and then click OK.

what happens when a global template is loaded and then later the file is deleted or unavailable ?
it stays in the list?
