Microsoft Office Document Inspector
Document Inspector lets you select the types of hidden content you want to retain in documents and check for sensitive or prohibited content you want to remove.
Many documents go through lengthy approval processes that involve multiple reviewers and contributors. Microsoft Office, like many other productivity applications, allows you to associate a wide range of details with a document—such as each reviewer's comments, name, organization, and the folder and server where the file is located—stored within the file for reference.
Privacy and confidentiality issues can arise if this hidden information remains in the final document after it is distributed. Document Inspector in Office 2007 and Office 2010 provides a central location for you to check for and delete hidden data and personal information in Microsoft Word, Excel, and PowerPoint files.
