...and a commercial version? I just purchased a download of Microsoft Word 2010 directly from the Microsoft website and notice that even after I rename a document, it still says "Microsoft Word non-commercial use" at the top of the window. What's the difference between a "commercial" version and the one I just bought? Is it just a matter of licensing for multiple copies (which aren't an issue with my version)? Is there any difference in functionality or features between the "non-commercial" version and the "commercial" one?
