I just did a clean install of Word 2007 in Windows 10. The default for new documents is that all the boxes in the autoformat as you type [ordinals, smart quotes, *bold* and _italics-] are checked. However, neither the *bold* nor _italics_ functions work, even though I have turned them on, and off, and on. And there are some functions, such as ordinals and smart quotes, that I cannot turn off, and that continue to work even after I uncheck the boxes. So there a set of functions that will and won't work at all times, irrespective of whether they are checked off as autoformat as you type.
