There are a few ways I can think of, such as coming from the factory with en engineering firmware, or a third party (manufacturer) tool pushing the update.
There’s also the question of how M$ would have even got the engineering firmware to begin with. If it did indeed get released through windows update, was it the manufacturer that provided it? M$ can’t really be expected to vet every driver they are provided.
What’s the other path for this firmware being related to the update?
Maybe I’m missing something
