> this "ads everywhere" has leaked into Windows 10 (though you can turn them off a bit).
Where? I've been using Windows 10 everyday for months and haven't seen an ad. There was that one time that something resembling a Tomb Raider ad was served to users' lock screens, but I never saw it myself and I've never seen anything else.
Mainly the start menu. Just because they aren't "random ads" like a Coke video, doesn't mean they aren't ads. Showing offers to buy software is definitely an ad.
I think there's pop-ups for Office as well as pre installed "apps" that are just links to buy.

Maybe it depends on which version of Windows 10?
