Windows 10 allows you to set live wallpapers and animated desktop backgrounds to customize your desktop. To set a live wallpaper or animated desktop background, you will need to first download a program such as DeskScapes or Wallpaper Engine. Once you have downloaded the program, you can select from a variety of live wallpapers and animated backgrounds. You can also create your own custom live wallpapers and animated backgrounds. Once you have selected the wallpaper or background you want, you can set it as your desktop background. You can also adjust the settings to make the wallpaper or background move or change over time. With these programs, you can easily customize your desktop and make it look unique.
