The Windows Error Reporting Service (WerSvc) reports errors when programs stop working or responding, and it enables existing solutions to be delivered. It also generates logs for the Problem Reports and Solutions diagnostic and repair service. If this service is stopped, programs and services that rely on this service will not report errors correctly, and the results of diagnostic services and repairs for those programs and services will not be displayed.
Windows Error Reporting is a feature that allows Microsoft to track and address errors that are related to the operating system, Windows features, and applications. Windows Error Reporting gives users the opportunity to send data about errors to Microsoft and to receive information about solutions. Solution information can include instructions for working around an issue, or a link to the Windows Update website or another website for updated drivers, patches, or Microsoft Knowledge Base articles. Developers at Microsoft can use Windows Error Reporting as a problem-solving tool to address customer issues in a timely manner and to improve the quality of Microsoft products.
Windows Error Reporting has "consent levels" that an administrator can configure to control how Windows Error Reporting sends data to Microsoft. These settings are configured on the Problem Reporting settings page of the Action Center Control Panel. These settings can also be configured through Group Policy under Computer Configuration or User Configuration in Administrative Templates\Windows Components\Windows Error Reporting\Consent.
User Account Control affects how Windows Error Reporting works. A standard user does not have the same ability to report errors as an administrator. If a prompt appears when a user is logged on as an administrator, the user can choose to report application and operating system errors. If a prompt appears for a user who is not logged on as an administrator, the user can choose to report application errors plus errors for operating system software that does not require administrative credentials to run.
The administrator also has the option to specify a list of programs for which error reports should never be sent.
This service is installed by default and its startup type is Manual. When the Windows Error Reporting service is started in its default configuration, it logs on by using the Local System account.
This service is not dependent on any other system service, nor is any service dependent on it.
