Microsoft added the Spotlight feature last year, and this is pretty much exactly what it was billed as: if you don&#x27;t have a lock screen image of your own, you get random wallpaper images from Bing, and also occasional app offers and tips. You can upvote&#x2F;downvote the offers to personalize the suggestions in the future. It&#x27;s an app discovery mechanism, and you can turn it off by picking your own lock screen image. I don&#x27;t know why it&#x27;s only in the news now. This isn&#x27;t the first time wallpapers for an app have been in the rotation.
