  • •The Bing Wallpaper app redirects desktop clicks to Bing.com without a disable option.
  • •This behavior is triggered once every 24 hours, making it less noticeable.
  • •Microsoft previously faced backlash for using the app for promotional purposes.

The Windows 11 Bing Wallpaper app has been reported to redirect users to Bing.com when they click on the desktop background. This behavior, described as adware-like, occurs without an option to disable it, unlike previous versions that included a toggle. The app reportedly triggers this redirection only once every 24 hours. This update follows Microsoft facing criticism for using the app to promote a Harry Potter TV series. Users have noted that the app encourages setting Bing as the default search engine and installing a wallpaper extension for Edge. While the app is optional, many users may find this behavior intrusive and annoying. The situation raises concerns about the increasing ad presence in Windows 11 amid competition from other operating systems.
