Quote:The German Federal Office for Information Security, BSI (Bundesamt für Sicherheit in der Informationstechnik) published a detailed Windows 10 Telemetry analysis on November 20, 2018.

The research paper, which is available in English (partially) and German, provides a deep analysis of Telemetry functionality that Microsoft implemented in the company's Windows 10 operating system.

he paper is based on Windows 10 version 1607 Enterprise. It covers:

• An overview of Windows 10's event tracing functionality for Telemetry.
  
• A technical analysis on how Telemetry data is collected and processed.
  
• An analysis of the network interfaces and connections used to transfer Telemetry data.
  
• A look at configuration and logging capabilities to monitor and control Telemetry data collecting.
  

The report is quite technical in nature and the first couple of pages are only available in German at the time of writing. You may want to skip ahead to page 9, Executive Summary, if you don't understand German; the English part of the report begins with chapter 1.2.
