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.
We don’t actually know that’s the case though.
What’s the other path for this firmware being related to the update?
Maybe I’m missing something
