Back in April, Microsoft released a non-security update for both Windows 7 and 8. This update, 3022345, created a new Windows service called the Diagnostics Tracking service. Microsoft describes this service as doing two things. First, it increase the amount of diagnostic data that the Customer Experience Improvement Program (CEIP) can collect in order to better diagnose problems. Second, it collects data for third party applications that use the Application Insights service. Application Insights is a preview that allows app developers to track performance issues, crashes, and other problems of their applications. The Diagnostics Tracking service collects this data and sends it to Microsoft.
