In the enterprise space (i.e. Windows 10 Enterprise users), users can fully opt out of Windows 10 telemetry, unlike everyone else but Windows 10 Education users. (Someone asked in the GitHub issue how that tool respects the various control levels over telemetry that Windows 19 offers, but the issue had turned into a shout-fest, so I'm not expecting the rank-and-file MS dev dealing with that issue to want to respond there.)
