A note: It's possible to disable the ads, but the only way to do so is to disable the random-lockscreen-images feature, which I actually rather like and appreciated before Microsoft started adding ads to it. Since up until now those ads have usually been for like… coupon books or something (seriously) I've just grumbled and tolerated it. Now MS is showing me ads for the AI plague, which is intolerable, so I guess I'm finally turning the feature off.
