Description

When users open documents Word automatically updates any links to external content, such as graphics, Excel worksheets, and PowerPoint slides. To disable automatic updating, the user can click the Office Button, click Word Options, click Advanced, scroll to the General section, and then clear the Update automatic links at open check box. If Word is configured to automatically update links when documents are open, document content can change without the user's knowledge, which could put important information at risk.
