comon - a WinDbg extension to trace COM

Comon is a WinDbg extension that can help you trace COM interactions (COM class creations and interface querying). You may use it to investigate various COM issues and better understand application logic. During a debugging session, comon will record virtual table addresses (for the newly created COM objects) and allow you to query them or even set breakpoints on COM interface methods. If COM metadata is available (either in the registry or in a standalone TLB/DLL file), you may load it into comon, and it will automatically decode COM identifiers.
