It’s not just Windows 10 that calls back to Microsoft; users have found that Visual Studio does it too. A manager has already apologized and provided a workaround. …coders have expressed concerns that Microsoft appears to be inserting calls to its telemetry service into binaries as they are compiled. Calls to telemetry_main_invoke_trigger and telemetry_main_return_trigger raised a few eyebrows having been found in both debug and release versions of the software. The good news -- maybe -- is that telemetry can be disabled. Over on Reddit, user sammiesdog triggered an active discussion following his discovery. It prompted a response from Steve Carroll, Development Manager for the Visual C++ team, who insists that the inclusion of the telemetry function is entirely innocent.
