Windows 10, version 1809 basic level Windows diagnostic events and fields

Article
10/01/2024

Applies to

Windows 10, version 1809

The Basic level 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. When the level is set to Basic, it also includes the Security level information.

The Basic level 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.

The following are true when the associated bit is set: consent was granted (0x1), consent was communicated at install (0x2), diagnostic data consent granted (0x20000), browsing data consent granted (0x40000).
Channel An integer indicating the channel of the installation (Canary or Dev).

One or more events is sent each time any installation, update, or uninstallation occurs with the EdgeUpdate service or with Edge applications. This event is used to measure the reliability and performance of the EdgeUpdate service and if Edge applications are up to date. This is an indication that the event is designed to keep Windows secure and up to date.

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.
