Agreed, shitty, but those aren't hard to disable, and it's one of the first things I do on new installs.

(I only run windows to do cross-platform testing)

For most users that get that nasty aftertaste, it's not as much that you can't remove or disable those ads/unexpected feeds, but that the manufacturer or core team that built it had the mentality to put it there in the first place.

I do not have ads at all and did not have to disable them. This maybe because when I install windows I do it using local account. Not the online account with MS. And of course I answer NOOOOOOO to every question they ask during install.
