Telemetry != Tracking
Telemetry data has been gathered since Windows XP and it's gathered in the magical Windows 7. It's not new. It's used to identify problems with their software and how it interacts with users systems. It's also used to understand how users are using the software and what issues they encounter.
Microsoft even provides documentation of everything captured under basic tracking.
