# Required diagnostic events and fields for Windows 11, versions 23H2 and 22H2
**Applies to**
- Windows 11, version 23H2
- Windows 11, version 22H2
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:

## Hang Reporting events
### Microsoft.Windows.HangReporting.AppHangEvent
This event sends data about hangs for both native and managed applications, to help keep Windows up to date. It doesn't contain any Watson bucketing information.

AppHang is reported only on PC devices. It handles classic Win32 hangs and is emitted only once per report. Some behaviors that may be perceived by a user as a hang are reported by app managers (e.g. PLM/RM/EM) as Watson Generics and won't produce AppHang events.
The following fields are available:
