Another method to change the desktop wallpaper in Windows is to open up the Personalize option on the desktop (called Properties in Windows XP). To do this, do the following:.
Right-click on the desktop and choose Personalize. (Or in the Windows 10 food selection, go to Setups > Customization > Background.).
In Windows 8/7/Vista through Control board's Customization applet, and in Windows XP through the Display Control board applet.
Under the Background dropdown, choose Image.
You can opt to use a pre-loaded image from Microsoft or choose Browse to find a different photo on your disk drive.
You can also decide if you want the image to fit, stretch, or fill the screen, or even for it to be tiled, centered, or covered across multiple screens.
Some variations of Windows have added alternatives here, like immediately changing the desktop wallpaper after so-many seconds, which can be found in handy if you do not wish to work out with just one background.
