Resize Your Wallpaper

If you just switched to a wide-screen monitor, your desktop wallpaper image may nolonger look right, or maybe you just want to make a small adjustment to it.For more-granular control of your wallpaper's placement, highlight the following key:

HKEY_CURRENT_USER\ControlPanel\desktop

Double-click the WallpaperOriginX icon in the right pane. 

If you don't see this icon,

Right-click in this pan choose New, String Value, type WallpaperOriginX to name the value, and press . Type a number (in pixels) for the starting horizontal position of your wallpaper's left edge, and press . 

Now double-click the WallpaperOriginY icon (create it if necessary as explained above) and enter a number for the starting vertical position of the image's top edge.

 If your wallpaper image is larger than the screen, type a negative number (for example, -200) to push the

picture's top or left edge off the screen.

To test the effect, first minimize the Registry Editor (and any other open window), 

right-click the desktop, choose Properties, and click OK or Apply to refresh the 

wallpaper placement. Repeat these steps as needed until the wallpaper is positioned 

correctly.The settings work whether you've set your wallpaper to be centered, tiled, or 

stretched.

NOTE :- Take the backup of your registry (by one of these Software's) before doing any tweak.
