Windows 7 / Getting Started

How WER Works

WER consists of the following conceptual components:

  • Report Processor
  • Data Collection Module
  • Transport System
  • Store Management System

Client-side WER functionality is provided through the WER service.

Report Processor

The Report Processor is a conceptual component that is responsible for managing the state of a report after it has been sent to WER. Applications use WER APIs to create and submit reports. At that point, the Report Processor decides whether to queue the report or submit the report. The Report Processor will attempt to hand over the report to the Transport System if the following conditions are met: there is network connectivity, the report is for an interactive application, and a user interface can be shown. Otherwise, the Report Processor will hand over the report to the Queue Management System. The Report Processor will also invoke the user interface component if applicable.

Data Collection Module

The Data Collection Module is responsible for collecting the following data:

  • Heap dump data
  • WMI query results
  • Registry key data
  • Registry tree data
  • Files
  • File version information
  • User documents
  • Minidump
  • Microdump (that is, a minidump that has been stripped of all other information except the faulting stack trace)

Transport System

WER uses two separate modes of transport:

  • Live Watson Mode In this mode, WER uses a four-stage protocol based on top of HTTP to communicate with the live Watson back-end servers.
  • Agentless Exception Monitoring (AEM) Support for the file share-based Corporate Error Reporting (CER) transport mode used in previous versions of Windows has been discontinued in Windows Vista. Instead, support for Agentless Exception Monitoring (AEM) has been added to Windows Vista for use in corporate environments. AEM is a component of the Client Monitoring feature in Microsoft System Center Operations Manager (SCOM) 2007 that lets you monitor operating systems and applications for errors within your organization.
