# Windows Error Reporting

## Introduction

[Windows Error Reporting(WER)](https://learn.microsoft.com/en-us/windows/win32/wer/windows-error-reporting) is an application error reporting technology built into Windows. By default, Windows systems enable error reporting for crashes, non-responses, and kernel faults in applications.

To quickly resolve issues on the Windows platform, Qualcomm® AI Engine Direct now uses this
infrastructure to generate application-specific problem reports and automatically notify Microsoft.

## Integrating Windows Error Reporting (WER) with Qualcomm® AI Engine Direct

Starting from version 2.28.0, Qualcomm® AI Engine Direct generates [WER generic event reports](https://learn.microsoft.com/en-us/windows/win32/wer/using-wer#windows-error-reporting-flow-for-generic-event-reporting)
for critical SDK errors. The application will continue executing after generating error reports,
with all Qualcomm® AI Engine Direct API usage and behavior remaining unchanged.

WER report generation is automatic and always enabled in the Qualcomm® AI Engine Direct.
However, report submissions are controlled by the end users’ Windows OS privacy settings.
