Documents that you create with Microsoft Word, a word processor from Microsoft Corporation, contain data that identify the user who created the file as well as the one who last saved it. While this functionality can be useful to track a project's progress, it can also allow third parties to gain access to confidential information. Fortunately, you can edit that information quickly and easily.
Open the Windows "Start" Menu. Click on the "Microsoft Office" folder, and then select "Microsoft Word" to launch the program.
Click on the "File" tab at the top of the screen, and then select "Options" from the left pane.
Edit the information under the "Personalize your copy of Microsoft Office" category. You can change both your username and your initials. Microsoft Word uses those two fields to identify the person who last saved a document.
