How to Create a Template Based on a Word 2010 Document
Rome wasn’t built in a day, but building your own Word 2010 document template can take even less time. You can easily create a Word template based on a document you’ve already slaved over. So, when the formatting and styles and all that junk have already been created, making a template is a snap — and doesn’t require a large army or navy nor any ambitious politicians:
Find or create a document.
Use a document that has styles or formats or text that you plan to use repeatedly.
Strip out any text that doesn’t need to be in every document.
The template should contain only the styles you need for that document, plus any text that's common to all documents.
Choose the Save As command from the File tab menu.
The Save As dialog box appears.
From the Save As Type drop-down list, select Word Template (*.dotx).
The document must be saved in a document template format. That’s what makes a template superior over a typical, boring Word document.
Click the Save button.
Your efforts are saved to disk as a document template, nestled in the proper place where Word keeps all its document templates.
Close the template by choosing the Close command from the File tab menu.
You close the template because any changes you make from now on are made to the template. If you want to use the template to start a new document, you choose that template from the New window.
