The fact that Raymond Chen is debugging these kind of issues, tells me Microsoft is short on staff that has his particular set of skills, handing him the hairiest issues from the annals of Windows. The new hires are probably all about .NET and JavaScript and what have you -- whatever Microsoft is about these days. I doubt it's C/C++. Chen is probably on standby and is paid handsomely as a de-facto VIP consultant. He is a legend, but he's becoming somewhat of a vintage developer.

Managed dump analysis in windbg was a thing. It’s been many years since I’ve needed it, though. Service telemetry improved quickly thereafter.
