The Dynamic Theme App for Windows 11/10, lets you set & automatically change Bing and Spotlight images as background & lock screen dynamically.

Windows 11's Spotlight feature is a pretty nice way to jazz up your desktop background with different wallpapers and fun facts when you hover over the image icon, but it takes up a lot of space.

Windows Spotlight feature is akin to Bing images of the day feature that allows you to set a picture as desktop background and lock screen image & register your vote to see more.
