Yes, you would need that for any disk media on the surface.
Surface, which is shorthand now for their Windows RT device line, uses an ARM processor. Windows RT and Office RT are programmed to run on ARM architecture. The operating system Windows RT is not available for retail purchase, ever--it's an OEM-level product. By the same token, no regular x86 software can be installed on a Surface RT.
Windows 8.1, whether Pro or not (versions), is compatible with x86/x86-64 type systems and is available for consumer purchase and upgrade. This is full-fat Windows.
(Now. Yes, this thread is located in the Surface Pro forum, but the side comment about Surface uses the shorthand assumption that it's the Windows RT device.)
You need to learn how to read and retain! Go read the OP again dude.....

The update is rather large (3.63 GB), so have a good wifi connection and plan to wait a while for the download to complete.
