Preview into Microsoft Office 2013

In addition to Windows 8, I have also been using Office 2013 over the past few months; I like some things, but not everything:
• Excel updates ripple slowly down the page; they seemed to run a bit faster in previous versions.
• The top-right Window icons have shifted somewhat; the Minimize icon ( _ ) is now in the middle rather than on the left while the Help icon is now on the left.
Since I rarely use the Help icon, but occasionally use the Minimize icon, I dislike this change
