To create a new document from a Word template, choose New… from the File menu. You see the New Document Task Pane appear:
Recently used templates are shown at the bottom of the window. Click one of the links and a new document will be created from that template.
If the template you want isn’t in the list, click the On my computer… link to display the full New Document dialog (below). Templates available are listed organised into pages. There is one page for each folder in your Templates folder (see Installing Word templates).
