Windows has a bad rep for gobbling up storage space on PCs. Ditto Surface.
So, what's devouring all of that flash storage space? On a 32GB Surface, Windows reports 29GB available. Subtract 5GB for Windows recovery tools, then another 8GB for Windows RT, Microsoft Office, and built-in apps. That leaves 16GB for the user.
On the 64GB model, you're left with 46GB.
Microsoft does offer advice on the same FAQ page about how to free up storage space, however.
Suggestions include using cloud storage via SkyDrive, using a microSD, microSDHC, or microSDXC memory card to add up to 64GB. or a USB flash drive or hard drive.
