Do you need to bother? What's the publisher going to do with the files anyway? Firstly it's unusual, to say the least, to print from an author's Word files without any copy editing, and secondly it's unheard of to print a copyright notice on each page of a book, so even if your Word files were to be taken as camera-ready surely the publisher would at least remove the footers?
(I'm not a publisher but I'm married to one and have picked up quite a bit about the book production process over the decades.)
If in doubt ask your editor. Editors might well be irritated by questions like this, but they'll be a hell of a lot more irritated if you deliver late because you've been spending time on things you didn't need to do in the first place.
