No matter how carefully you originally design your templates, you will sooner or later want to make some improvements.
Follow these steps to make changes to a template:
The preceding set of steps involves opening a template and making changes to it directly. This is not always necessary, however. When you close a document based on the Normal template after you've added, modified, or deleted any of the items you can store in templates (styles, toolbars , AutoText entries, and macros), Word automatically saves these changes to the template.
When you close a document that is based on any template other than Normal, Word first asks whether you want to save changes to the document (if you have unsaved changes). If you have added, modified, or deleted any of the four items you can store in templates, Word then asks whether you want to save changes to the template. Click the Yes button to retain the changes.
