The Debug Diagnostic Tool (DebugDiag) from Microsoft is designed to assist in troubleshooting issues such as hangs, slow performance, memory leaks or memory fragmentation, and crashes in any user-mode process. It is especially useful for capturing and analyzing WebStatistica issues. 

Windows OS

6). On "Advanced Configuration", set "Action type for unconfigured first chance exceptions" to "Mini Userdump" and click "Next >".
