Office 2013 is set to save your documents to SkyDrive by default. We’ve already showed you how to make Office save to your computer instead. But no matter where you save your documents, you might not need to see the Save As Backstage view each time you save a new document.
To change it, click File > Options.
Now under the Save Options, uncheck “Show additional places for saving, even if sign-in may be required” and click OK.
Now when you save a new document by hitting the Save icon on the Quick Access bar, or hitting Ctrl + S, you’ll get the traditional Save As Explorer screen instead of the Backstage view.
If you do want to get the Backstage view, click File > Save As.
