Anyway, to me this sounds like some popular office OS has made its
way into the cockpit and was out for lunch with the HDD while the
pilot
was trying to talk it into delivering his commands to the engine
controllers...

Windoze is NOT qualified for critical applications like this. It's
something pretty specialized and focused for the application. I
suspect the investigation will either find a hardware fault or
operator error (misconfigured autopilot). Airbus has had something
similiar happen, resulting in a crash and loss of life.

I know some of the guys who do the engine control computer firmware
for the Pratt&Whitney engines. They use our gear to simulate engine
sensor signals to the control computer, and run weeks/months of
scripts to verify the firmware in all sorts of situations.

Their ECC's use no OS at all, just basic bare-metal state machines.
