Microsoft collects Windows diagnostic data to keep Windows up-to-date, secure, and operating properly. It also helps us improve Windows and, for users who have turned on “tailored experiences”, can be used to provide relevant tips and recommendations to tailor Microsoft products to the user’s needs. This article describes all types diagnostic data collected by Windows at the Full telemetry level (inclusive of data collected at Basic), with comprehensive examples of data we collect per each type. For additional, detailed technical descriptions of Basic data items, see Windows 10, version 1703 Basic level diagnostic events and fields.
The data covered in this article is grouped into the following categories:
- Common Data (diagnostic header information)
- Device, Connectivity, and Configuration data
- Product and Service Usage data
- Product and Service Performance data
- Software Setup and Inventory data
- Content Consumption data
- Browsing, Search and Query data
- Inking, Typing, and Speech Utterance data
- Licensing and Purchase data
The majority of diagnostic data falls into the first four categories.
Most diagnostic events contain a header of common data:
