Whenever you open or save a document in Microsoft Word 2003, Word adds the document title to your recent history, accessible through the "File" menu. This feature lets you quickly locate recently used files so you can continue working on them. However, this easy-to-find list of recent documents also lets other users see what documents you have been working on or viewing. To prevent this, Word allows you to clear this history or remove the feature entirely.
Open Microsoft Word 2003, then click "Tools" on the top menu and select "Options."
Click the "General" tab.
Uncheck the box next to "Recently used file list," and click "OK." The recent history will be cleared and the history feature will be disabled. Re-check the "recently used file list" to enable the feature, but keep the previous history cleared.
