A:Answer Hi there.
Thank you for your post. In regards to your question, yes, Surface RT does have a desktop mode. It comes pre-installed with the preview version of Office Home and Student 2013 RT which includes Microsoft Word, Excel, PowerPoint, and OneNote. Upon set up the preview can be updated to the full version for free via "Windows Update". Surface RT works exclusively with apps available in the Windows Store, so I recommend checking out the great selection of apps to get more of an idea of all of the things you can do with Surface.
