It sounds like the task of preventing your Windows 10 PC from phoning home is going to be a full time job.
The Group Policy pack Privacy and Telemetry, short gp-pack PaT, is a collection of 70 policies designed to disable sending data to Microsoft on Windows 10 devices. Windows 10 Pro and Enterprise administrators may use the Group Policy to modify privacy settings, and block some telemetry collecting and submitting to Microsoft. Numerous privacy tools for Windows 10 have been released that modify Registry keys directly. Several of the programs go further, for instance by removing applications that ship with Windows 10, or blocking Microsoft Telemetry servers on the system.
