仅限Windows：免费的Microsoft Office“删除隐藏数据”加载项会删除嵌入Word、Excel和PowerPoint文档中的元数据，您不希望其他人看到这些文档。

《今日美国》科技专栏作家评论：

任何使用Word的人都有暴露敏感信息的风险。Word**元数据（有关数据的信息），以帮助识别作者姓名、文档标题、关键字、打印和保存日期，以及审阅和保存文档的人员姓名。元数据还可能泄露您的营业地：您的公司或组织的名称、保存文档的网络服务器或硬盘驱动器的名称以及添加的任何注释。

外接程序在“文件”菜单中**“删除隐藏数据”项，也可以从命令行使用该项。《今日美国》提供了更多技巧，帮助您避免业务文档的额外隐藏数据被错误的人看到：

• Turn off Fast Save. This feature speeds up saving a document by saving only changes made to a document. However, text that you delete from a document may still remain. Microsoft recommends turning off this feature to eliminate any chance of deleted text remaining in the document. Click Tools, then Opti***. Click the Save tab. Clear the "Allow fast saves" check box and click OK.
• You can remove personal information from a document when you save it. In Word 2002 and 2003, click Tools, then Opti***. Click the Security tab. Under Privacy opti***, select "Remove personal information from file properties on save" and click OK. In Word 2000, click Tools, the Opti***. Select the User Information tab. Clear the information in Name, Initials and Mailing Address and click OK.
• Turn off the Track Changes tool. In Word 2002 and 2003, click Tools, then Track Changes. In Word 2000 and earlier versi***, click Tools, Track Changes, Highlight Changes. Click to clear the check mark in the "Track Changes while editing" box. You can tell if the Track Changes feature is on by looking at the status bar (located at the bottom of every document). When Track Changes is enabled, TRK appears in the status bar. When Track Changes is disabled, TRK is dimmed. Track Changes must be disabled before writing the document. Otherwise, any changes made will not be removed.
