Microsoft Word 2007: Change the author name for documents 
Every time you create a new document, Microsoft Office Word sets the Author property based on the User name setting that appears in the Word Options dialog box. The User name setting also provides the name and initials that are displayed in comments and tracked changes.
Change the author name in an existing document
1. Click the Microsoft Office Button Button point to Prepare, and then click Properties.
2. In the Document Information Panel, type the author name in the Author box.
Note: Changing the Author property in the Document Information Panel of an existing document has no effect on the User name setting in the Word Options dialog box.

Property box can also be used to fill in the name/title of the document.
This might seem little useless but if you create your PDF file, these “property” fields are transferred into the description of the PDF. If you put the file on the internet, search engines tend to use these fields in order to index your document.
So properly filling properties gives you higher chance to be indexed by google and others.
