How to Change desktop background in windows 7,8,8.1
 Right-click your desktop and choose Personalize.
The Personalization window appears.

Select Desktop Background from the windows’ bottom left.
The window shown here appears.

Click a new picture for the background.
Be sure to click the drop-down list to see all the available photos and colors that Windows offers. To rummage through folders not listed, click the adjacent Browse button. Feel free to search your own Pictures library for potential backgrounds. When you click a new picture, Windows immediately places it across your desktop. If you’re pleased, jump to Step 5.
Decide whether to fill, fit, stretch, tile, or center the picture.
Not every picture fits perfectly across the desktop. Small pictures, for example, need to be either stretched to fit the space or spread across the screen in rows like tiles on a floor. When tiling and stretching still look odd or distorted, try the Fill or Fit option to keep the perspective. Or try centering the image and leaving blank space around its edges. You can automatically switch between images by choosing more than one photo. (Hold down Ctrl while clicking each one.) The picture then changes every 30 minutes unless you change the time in the Change Picture Every drop-down list.
Click the Save Changes button to save your new background.
Windows saves your new background across your screen.
