Another method to change the desktop computer wallpaper in Windows is to open the Personalize choice on the desktop computer (called Properties in Windows XP). To do this, do the following:.
Right-click on the desktop computer as well as pick Personalize. (Or in the Windows 10 menu, go to Settings > Customization > Background.).
In Windows 8/7/Vista via Control Panel's Customization applet, as well as in Windows XP via the Show Control Panel applet.
Under the Background dropdown, pick Photo.
You can choose to use a pre-loaded picture from Microsoft or pick Browse to find a different image on your hard disk.
You can also determine if you desire the image to fit, stretch, or load the display, or even for it to be tiled, centered, or spanned throughout multiple displays.
Some versions of Windows have extra choices here, like immediately transforming the desktop computer wallpaper after so-many secs, which comes in useful if you don't want to work out with just one background.
