I have saved templates but I don't know how to open them. Any help.
Try using Windows Explorer to go to the folder where you saved the templates,
and double-clicking the icon of one. That will create a new document based on
that template.
Or in Word you can click File > New (in Word 2007, click Office button > New)
and select "On my computer...", then use the dialog to go to the correct folder
and select the template you want.
