Werfault.exe is a Windows Error Reporting process of Windows Vista. This feature allows parent company (Microsoft of course) to evaluate and fix application problems in Windows OS (which is your Operating System). The tool enables Windows end users to report internal error data and receive possible updates and specific solutions to the reported error. The Werfault.exe executable allows Windows developers to locate and target any reported errors and enhance the overall stability of Windows.
End users can decide to either turn Windows Error Reporting feature on or off and no personal information is reported back to Microsoft during the transmission. Microsoft has built in the ability to personalize the reporting feature, allowing full control to users. If you choose to only select certain executables or program files to send back error reports, you can create an actual block list so only certain applications allow reporting.
Possible Problems Caused By Werfault.exe
One of the common issues caused by Werfault.exe is that your PC becomes extremely slow to respond and process input. If you check your Task Manager, it will often report that the CPU utilization is maxed out near 100% consistently, and the the Processes tab will show more than one instance of Werfault.exe using up all available CPU resources.
