HOW TO SET THE WINDOWS DESKTOP BACKGROUNDS:
The simplest way to set a picture as the desktop wallpaper is to open it so that you can see the image, and then right-click it to choose Set as desktop background.
You also see this option when you right-click the picture file in Windows Explorer; you don’t even have to open the picture to set it as the desktop wallpaper.
Another way to change the desktop wallpaper in Windows is to right-click the desktop itself and select Personalize (or Properties in Windows XP). From here, you can choose a new desktop background image as well as decide if you want the photo to be tiled, centered, or stretched across the screen.
Change the Windows 10 desktop background and colors:
Select the Start button, then select Settings > Personalization to choose a picture worthy of gracing your desktop background and to change the accent color for Start, the taskbar, and other items. The preview window gives you a sneak peek of your changes as you make them.
In Background, select a picture or solid color, or create a slideshow of pictures.
In Colors, let Windows pull an accent color from your background, or choose your color adventure.
After you’ve selected an accent color, decide where you want to see it show up, and whether it looks better in a dark or light setting.
