Was doing some more reading on the surface and came across the software update process:

For Windows RT Surface users, the update can be had by:

Head to the Control Panel version of Windows Update, not the Metro-accessible version that you use for more everyday settings changes.
Fire up a search for ‘Windows Update,’ and select ‘Install optional updates,’ instead of ‘Windows Update’ from the list of results.
If no updates are available, have the device run a check. If there are, then get going right away. The update is titled “Update for Microsoft Office Home & Student 201[3] RT Preview.”
Select it, and install.
Reboot.

Speaks for itself.
