The Surface RT device ships with pre-installed Office 2013 Home & Student Edition Preview software. Being a preview, there are some issues that need fixing.
Thankfully, an update is available, which fixes all problems and removes the “Preview” tag from the application splash screen.
The update is available via Windows Update. If you do not see the update in Windows Update, follow the steps below:
1. Open the Search option on the charm bar, and type “update” in the search box. Press ENTER.
2. Choose the “Install Optional Updates” from the search results. This will fire the desktop version of Windows Update.
3. Under optional updates, select the update for Office 2013 Home & Student Edition (586 MB) and install it.
