WER Service
The WER service is responsible for obtaining the information that is provided to the back-end Watson servers when an application exception occurs. The service library, Wersvc.dll, is hosted in its own Svchost.exe process. When a process crashes, the WER service calls Werfault.exe (or Werfaultsecure.exe, discussed later in this section) to obtain all of the necessary data for the crashing/hanging process. Werfault.exe loads Dbgeng.dll and Dbghelp.dll to collect the application error data. It also loads Faultrep.dll to perform the reporting to the back-end Watson servers. If the WER service is not started when an application exception occurs, Werfault.exe and the dependent libraries will still be started to perform the data collection and reporting tasks for the fault.
WER in Windows Vista and later also supports error reporting for secure processes. Secure processes are processes that contain data encrypted with a private key and restricted permission. If a crash occurs in a secure process, the WER service uses Werfaultsecure.exe to obtain the necessary data for the crashing/hanging process. The report is encrypted when created and queued automatically to prevent any possibility of exploitation through the user interface. The encrypted data is then sent to the back-end Watson servers, where it is decrypted and analyzed.
