First published on August 19th, 2015 as version 1.0, Spybot Anti-Beacon is a tool to block telemetry. When Windows 10 was released, the outcry about the massive amount of telemetry, compared to previous Windows versions, was huge. Just like with Spybot, Anti-Beacon was initially a small tool for his own use to disable Windows 10 telemetry. It had the working name Cut The Line before its release, referring to stopping the Internet connection.
Since then, Anti-Beacon has grown to cover further categories of software that have also implemented telemetry, like office software, browsers, even antivirus applications.
