Windows Compatibility Telemetry seems to have reached new levels of malice. It now appears not just to be scheduled (like when you boot up), but appears to start whenever you installed/updated new software.
At this point, I wonder whether there's watchdog software out there which can simply kill the process as soon as it starts running. Does anyone know of such a tool? Because clearly MS isn't about to CEASE AND DESIST their disk-trashing operations on their own.
