Telemetry is an automated communications process by which measurements are made and other data collected at remote or inaccessible points and transmitted to receiving equipment for monitoring.
so its reading all your data from the hard drive and sending it off some where . right ???
go read up on it, it does what it says on the tin...
ive been using it since 2 days after win 10 went live and it blocks pretty much all the telemetry and ms crapware.
if it didnt work i wouldnt recommend it...
