WerSvc or Windows Error Reporting Service allows errors to be reported when programs stop working or responding and allows existing solutions to be delivered. Also allows logs to be generated for diagnostic and repair services. If this service is stopped, error reporting might not work correctly and results of diagnostic services and repairs might not be displayed.
To do this, Run services.msc. Locate Windows Error Reporting Service. Right-click on it and select Properties. Change its startup type, from Manual to Disabled. Click OK and restart your computer.
This should help stop both types of errors, viz WerMgr.exe Application Error and WerMgr.exe Application Error.
You can also use the Windows Registry to enable or disable Windows Error Reporting Service.
