Can confirm that Tektronix is using Windows also, though I think they had been for quite some time. Seems like a really odd design decision for an appliance. I would probably tend towards like FreeRTOS (or at least some variation of an RTOS). On the other hand the EEs I’ve worked with also use their scopes as workstations with external monitors and everything, so maybe that’s part of it.
