By setting a universal wallpaper for both the desktop and the start screen in Windows 8.1, you will minimize the feeling that these were meant to be two different experiences.
Choose the “Personalize” option from the “Settings” charm on the start screen and you’ll see your current desktop wallpaper appear as the final option. This simple act will create a sense of unity between both screens that is lacking when the start screen is set to any of its default wallpapers.
- Open “Start” by swiping in from the right edge of the screen and then tapping “Start” (or, if you’re using a mouse, point to the lower-left corner of the screen, move your mouse all the way into the corner, and then click “Start”)
- Swipe in from the right edge of the screen, and then tap “Settings.”
(if you’re using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click “Settings”)
- Tap or click “Personalize,” and then tap or click the preview of your desktop background.
