Microsoft Faces Backlash Over Harry Potter-Themed Ad in Bing Wallpaper App

The wallpaper app, which usually displays neutral travel or animal scenes, appears to be showing a huge ad for the new Harry Potter series coming to HBO Max.

Microsoft's tactic of injecting ads into its products is sparking new backlash after its Bing Wallpaper app began displaying an intrusive Harry Potter-themed promotion. 

The optional app usually picks appealing but innocuous images of travel scenes and animals as daily wallpapers on Windows PC desktops. But on Monday, a few users complained that Bing Wallpaper was pushing an ad after they selected an image of a castle titled Harry Potter Fantastic Beasts 11-Film Collection.

“I have been using Bing Wallpaper happily for years. Today, for the first time, I noticed a hecking ad in place of my wallpaper,” wrote one user on a Thurrott.com forum. “Why this level of nickel and diming. This is atrocious UX, it’s ad over [an] entire screen. For a moment I thought I installed some adware malware.”

The wallpaper seems to be a tie-in to promote the new Harry Potter series, slated to premiere in December on HBO Max, but users are not happy. “Always enjoy the photos but saw this today. Sent feedback and disabled. Harry Potter of all things. WTF,” wrote one Reddit user. 

Another user also criticized the company in a Microsoft Learn article, and pointed to Harry Potter author JK Rowling and her controversial views on transgender people. “Why is my Bing wallpaper advertising a transphobic author's films on my desktop?” they wrote. “Will there be more advertisements, and if so, must I uninstall Bing wallpaper now to prevent them, or is there a way to opt out?”

So far, Microsoft hasn’t responded to a request for comment. But it’s not a great look for Redmond, given that the company has been vowing to improve Windows 11 partly by decluttering the OS.
