At least on Pro / Enterprise / Education edition there are no ads. Maybe I have disabled them, no idea. It could be that this is a thing in Home edition that cannot be easily disabled, have never used Home edition in my life to be honest.

Recall is an optional feature that will run on specific CPUs and it will be local unless something recently changed. Would I use it even if I could? No, I don’t see a need, but it probably will be useful to many.
