windbg-user-exception-triage
Use when a native C/C++ app, service, or user-mode driver host (including UMDF) crashes with a structured exception in a dump or WinDbg session, including native faults inside managed processes. Not for managed .NET exceptions, WinUI/XAML app errors, or kernel bugchecks.

# User-Mode Exception Triage
**Load `windbg-diagnostic-method` first** if it is not already loaded in this
conversation, and apply it throughout for evidence ranking, hypothesis testing,
confidence calibration, independent review, and report validation. This skill
adds the bug-family-specific commands and evidence requirements.
## When to use
Start here for access violations, heap corruption, stack overflow, fail-fast,
breakpoints, and other structured exceptions in a native application, service,
or user-mode driver host process dump. This includes UMDF driver failures that
occur in their user-mode host. Confirm
the dump type from WinDbg; the filename extension alone does not distinguish
