A preference will be used if wanted to set a default wallpaper background for all machines in your company, but still wanted users to be able to set their own wallpaper.
More about a wallpaper:
A wallpaper, also known as a desktop background, is an image that appears when the user's desktop is visible behind the graphical user interface. It is the image, color, or pattern that appears on your computer's main OS screen when it first boots up.
It's simple to change the desktop backdrop on Windows. Depending on whether the image is open right now, there are two approaches.
Right-click or tap-and-hold the image while it is open, then select Set as > Backdrop. Alternatively, in earlier versions of Windows, you may also select Set as > Set as background or Set as desktop background.
