Windows Error Reporting Service (WerSvc) Defaults in Windows 7

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.

Default Behavior

Windows Error Reporting Service is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Windows Error Reporting Service is started, it is running as localSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Windows Error Reporting Service fails to load or initialize, Windows 7 startup continues without error messages. The failure details are being written into Event Log.

Restore Default Startup Configuration for Windows Error Reporting Service

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config WerSvc start= demand

3. Close the command window and restart the computer.

The WerSvc service is using the WerSvc.dll file that is located in the %WinDir%\System32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
