If you have a Microsoft system, your system is constantly leaking data to Microsoft. Smartscreen for the OS and web browser, in the name of security, are constantly sending data about what you're downloading, what sites you go to, what apps you're running/installing, etc. to supposedly help keep you safe while MS collects all that data and does who knows what with it. You can try to kill parts of it with local and/or group policy, but you cannot completely kill it (just like the other telemetry they collect).
