My apologies if this question has been answered before. I did several searches and couldn't find anything.
I use a very small subset of typefaces: maybe 3-5 with Word and Excel and 6-8 with PowerPoint. I've disabled the fonts I don't need using Font Book, but even after restarting, they still show up in the Office menus.
I'm running the latest version of Office (14.4.6) and Yosemite (10.10.1) on a MacBook Pro retina display, late 2013.
