The best way of doing that is to create a custom toolbar IMO and then just use the Boot straight to desktop.
Metro is still a pain -- in my post on experience with it -- You can alter the size at will of TWO metro apps (Vertically on the screen). A 3rd one can start - you see a horizontal small screen appear but when you click on it one of the other metro apps disappears so you STILL only get TWO on the screen and you can't CONCURRENTLY view classical desktop apps like say a Spread sheet you are working on -- so for serious desktop users - Metro still a NO NO.
(With Multiple monitors though you can still use desktop apps on another screen - a small improvement).
Boot to the desktop directly though is a HUGE improvement.
