As Stefan noted above, the two icons that you are missing are the Ribbon display option and the question mark to access Word Help (which can also be achieved using the F1 key). In any case, I do not have Word 2016 so I don't know if you are missing anything. Here is a link that I googled trying to find a resolution:
