This must be the seventh time I've right-clicked and uninstalled these stupid "Get Office" and "Candy Crush Soda Saga" apps. Windows 10 is missing an "UNINSTALL AND NEVER DARKEN MY DOOR AGAIN, GODDAMN YOU!" option.
I've never touched Candy Crush, yet I noticed in the resource handler the other day that it had been using 100K of network traffic, that day only. If one would be on a network with a quota and data prices, many 100K posts will over time eat your quota.
Interesting. That's the same reason I disable Live Tiles on the Start menu: you never know how much background downloading is going on to keep those current.
