Microsoft has repeatedly been criticized for collecting a lot of telemetry data in Windows 10. The company has proved that it listens to the opinion of its customers and, with the release of updates, has provided users with greater control over confidentiality. Nevertheless, according to IB-expert Mark Burnett, who devoted many years to the development of Windows, even restrictive settings do not prevent Windows 10 Enterprise Edition from sending data to Microsoft servers.

As explained by Barnett, Windows 10 Enterprise Edition users can really turn off telemetry, but even with the instruction it's not so easy to do. Users will have to change almost all the default settings, sometimes just a few for the same function. In the instructions, such changes are not welcome, since they reduce the performance. "Most likely, they just do not want you to set the settings yourself," the expert said..

Barnett installed Windows 10 on a computer with a VirtualBox virtual machine (with CentOS host OS) without a network card and applied Windows Restricted Traffic Limited Functionality Baseline, a Microsoft-developed configuration for Windows 10 that disables most of the tracking functionality. Then the expert disconnected the virtual machine, activated the network traffic tracing and left for the night.

As it turned out, most of the traffic was actually cut, but some data was still sent to the Microsoft server. Windows still sent telemetry data about the programs used, application diagnostics, Windows DRM, and also about what the "Calendar" and "Mail" have access to.
