There is no practical way of turning of telemetry completely.

Since telemetry is enabled by default, I doubt the portion of users turning it off is significant. I think the bigger problem is that you just can't derive meaningful data from telemetry to make the necessary decisions for improving user experience.

Windows 10 Enterprise and group policy to disable telemetry? Agree it's not exactly "practical" though for non-business settings.
