What hidden things is your MS Office document telling people?
A little known piece of information is that Office documents contain "document information" that is often auto-generated, some of which can be based on information that was entered when the Office application was first installed. This can include your name and company. Open any Word document you might have, for example, and take a look at the document properties. To do this, from the File menu select Properties and click the Summary tab. A window similar to the below will be displayed. You might be surprised by what's there!
