There is a post about the inconsistent wizard titlebars in Vista and 7, for example. (There is a "back" button in the top left, but there is space above it. The reason is they didn't want to or couldn't do ownerdraw stuff on the titlebar, and then later stuck with it. The original plan was to have it look like in the Windows Vista/7 installer, where the back button is vertically centered in the titlebar). https://web.archive.org/web/20070206051159/http://shellrevea...
