When you open an Office 2013 program, a start screen automatically displays showing you the various templates available and a list of recent documents opened in the left column. If you find this screen annoying and would rather pass it by, it’s easy to disable.
It's not annoying, It's rather entertaining. I like welcome screen of any app, it make my day!
What's the point to play with the Registry when one can disable it on the first screen of the Options window?
The registry edit effects every app in the Office 2013 suite whereas if you do it through options you must do it individually for each app.
