I thought it can be switched off in the enterprise version of Windows 10? AFAIK that's the only way how Microsoft was able to start convincing companies to switch from Windows 7.
They do provide a GPO object to turn off the "Telemetry" for Enterprise versions.
But it still installs the entire Windows store with Candy Crush Saga, Facebook, Minecraft, XBOX, etc. and they make it nearly impossible to remove. Why on earth they would force that crap down the throat of their ENTERPRISE customers is beyond me.
I fought with it for months and finally gave up and cancelled the deployment project until MS offers a better way for enterprises to control the Window Store.

IE: When trying to build a secure environment, you must eliminate all unnecessary attack surfaces. The customer did not need "XboxIdentityProvider" installed their Windows 10 Enterprise environment. But this is something MS feels must be installed on all Windows 10 PCs thus they made it nearly impossible to remove.
