Registry: Change the Position of the Desktop Wallpaper (Windows 9x and NT)

Unfortunately Windows only gives you the limited options of center or tile for the placement of the desktop wallpaper. With this setting you can move the image anyway on your desktop.
Open your registry and find the key below.

Key: [HKEY_CURRENT_USER\Control Panel\Desktop]
Value Name: Wallpaperoriginx, Wallpaperoriginy
Data Type: REG_SZ
Data: Distance in Pixels

Create two new string values of 'Wallpaperoriginx' and 'Wallpaperoriginy'. If the values already exist then you simply modify them.
Set the value of 'Wallpaperoriginx' to equal the horizontal offset, and set the value of 'Wallpaperoriginy' to equal the vertical offset. Then either restart Windows, or change your background image through the Control Panel.

Note: The image is offset from the center of your desktop, so you can use positive and negative values.
