STATUS_UNHANDLED_EXCEPTION
The original exception escaped all applicable handlers
This status is a wrapper-level result indicating that exception dispatch reached the unhandled path. It does not identify the underlying fault. The useful evidence is the original exception code, address, parameters, and stack before top-level filtering or Windows Error Reporting changed the context.
A broad SetUnhandledExceptionFilter callback can record the event but generally cannot make arbitrary corrupted execution safe. When telemetry contains only STATUS_UNHANDLED_EXCEPTION, update the capture path to retain nested or preceding exception records. Also check whether a language runtime translated its own exception into SEH and discarded the original type or message.
What to inspect
- Find the original exception record and first-chance event before the wrapper status.
- Capture the faulting thread context and loaded-module list.
- Review top-level filters that overwrite, translate, or suppress exception data.
- Treat continuation as unsafe unless the original exception contract permits it.
