From a security standpoint you wouldn’t want to share these data with others (when you send these documents electronically). With this add-in you can permanently remove all these hidden data from MS Word 2003/XP, Excel 2003/XP, and PowerPoint 2003/XP files.
Download ‘Remove Hidden Data’ add-in from Microsoft and install it. After finishing your document, save it (preferably in a different file name). Open, for example Word, click ‘File’ menu and select ‘Remove hidden data’. Select the document for removing Meta data and follow the instruction.
[Alternatively, you can do it without the add-in, go to ‘Tools’ – ‘Options’ and click on ‘Security’ tab. Check the box ‘Remove personal information from this file on save’ and click OK to save]
The Remove Hidden Data add-in does not work with Information Rights Management-protected or digitally-signed files. This add-in is not compatible with the 2007 Office system. The Document Inspector feature in the 2007 Office system replaces this add-in. More details and download
