About this update
This package updates the Diagnostic and Telemetry service on existing devices. This package also supports applications that are subscribed to Visual Studio Application Insights. The content in this article was revised to more accurately reflect the functionality of the package and related Windows Service.
About the Diagnostic and Telemetry service
Helping the overall application experienceThe Diagnostic and Telemetry service collects diagnostics information about functional issues on Windows systems that participate in the Windows Customer Experience Improvement Program (CEIP). CEIP reports don't contain contact information, such as your name, address, or telephone number. This means CEIP won't ask you to participate in surveys or to read junk email, and you won't be contacted in any other way. Windows users can make changes to their Windows CEIP participation in the Windows Customer Experience Improvement Program settings page by opening Control Panel and selecting Action Center > Change Action Center settings > Customer Experience Improvement Program settings.
Applications that have their own diagnostics and telemetry program such as Application Insights may depend on the service to transport the telemetry to Microsoft. Application users will be able to participate in these programs through the settings of the application.
Additional informationThis update uses SSL (TCP Port 443) to download manifests and upload telemetry to Microsoft that uses the following DNS endpoints:
Windows 7 supportThe Windows 7 offering also supports the kernel updates that were deployed separately to Windows 8.1 through security update 3045999.
