Not all Windows users are seeing this Harry Potter ad, mainly because Bing rotates its wallpapers and varies them depending on the user’s region. According to Windows Latest, “One user told Windows Latest that they used four PCs on the same day, and only one showed the Harry Potter ad. The other three had a nice view of Bamberg, so not everyone appears to be getting the same wallpaper.”
The fact that the Bing Wallpaper app is now pushing full-size ads to Windows PCs is surprising. Microsoft recently admitted that it has been displaying too many ads in Windows, but the fact that the entire desktop background is being commandeered as a new avenue for marketing was never explicitly announced by Microsoft. (However, if you look at the small print, Microsoft reserves the right to display ads within wallpapers.)
Bing Wallpaper is part of Windows 10 and 11 and facilitates automatic desktop background changes, primarily intended to liven things up and treat users with a new visual image and vibe every day.
