I thought I had read that there were ways to shut off all the MS telemetry via hidden settings or registry changes.

Cortana can also be disabled by quickly deleting or renaming a file somewhere, after killing a process. Specifics can be googled.

There are ways to disable all of the various data collection mechanisms but they aren't sanctioned by Microsoft and MS provides no user interface for them. There are several projects on Github that perform varying degrees of this.

The same goes for Apple's collection mechanisms.
