Article
10/01/2024

Applies to

Windows 11, version 21H2

Required diagnostic data gathers a limited set of information that is critical for understanding the device and its configuration including: basic device information, quality-related information, app compatibility, and Microsoft Store.

Required diagnostic data helps to identify problems that can occur on a particular device hardware or software configuration. For example, it can help determine if crashes are more frequent on devices with a specific amount of memory or that are running a particular driver version. This helps Microsoft fix operating system or app problems.

Use this article to learn about diagnostic events, grouped by event area, and the fields within each event. A brief description is provided for each field. Every event generated includes common data, which collects device data.

You can learn more about Windows functional and diagnostic data through these articles:

Microsoft.Windows.FaultReporting.AppCrashEvent

This event sends data about crashes for both native and managed applications, to help keep Windows up to date. The data includes information about the crashing process and a summary of its exception record. It doesn't contain any Watson bucketing information. The bucketing information is recorded in a Windows Error Reporting (WER) event that is generated when the WER client reports the crash to the Watson service, and the WER event will contain the same ReportID (see field 14 of crash event, field 19 of WER event) as the crash event for the crash being reported. AppCrash is emitted once for each crash handled by WER (e.g. from an unhandled exception or FailFast or ReportException). Note that Generic Watson event types (e.g. from PLM) that may be considered crashes" by a user DO NOT emit this event.

The following fields are available:

AppName The name of the app that has crashed.
AppSessionGuid GUID made up of process ID and is used as a correlation vector for process instances in the telemetry backend.

Channel An integer indicating the channel of the installation (Canary or Dev).
client_id A unique identifier with which all other diagnostic client data is associated, taken from the UMA metrics provider. This ID is effectively unique per device, per OS user profile, per release channel (e.g. Canary/Dev/Beta/Stable). client_id isn't durable, based on user preferences. client_id is initialised on the first application launch under each OS user profile. client_id is linkable, but not unique across devices or OS user profiles. client_id is reset whenever UMA data collection is disabled, or when the application is uninstalled.

pop_sample A value indicating how the device's data is being sampled.
reactivationBrandCode Contains the 4 character reactivation brand code or distribution tag that has been assigned to a partner. Not every Windows install will have a brand code.
session_id An identifier that is incremented each time the user launches the application, irrespective of any client_id changes. session_id is seeded during the initial installation of the application. session_id is effectively unique per client_id value. Several other internal identifier values, such as window or tab IDs, are only meaningful within a particular session. The session_id value is forgotten when the application is uninstalled, but not during an upgrade.
