HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection add a new 32 dword "AllowTelemetry" and set the value to 0.

Then, open Services and stop & change startup to disabled on "Connected User Experiences and Telemetry" and "dmwappushservice".

There are bunches of tools and scripts around to do it, but those 2 things are really all that you need to do. Microsoft doesn't stop you from "opting out" of Telemetry by making these changes. All windows updates / etc still work.

I'm pretty sure some reporting and telemetry is still active even after doing those things, unless you run Windows 10 Enterprise.

You can get around that by blocking it with a (non-Microsoft) firewall though.
