I found this in a few different places around the 'net - hopefully it's helpful:
Restore Shortcuts
If a shortcut that you want is removed, follow these steps to restore the shortcut:
- On the Desktop, double-click the Unused Desktop Shortcuts folder. The Unused Desktop Shortcuts dialog box is displayed. Note: If the Unused Desktop Shortcuts dialog box is maximized, click the Restore Down button (appears to the left of the red Close button).
- Drag the shortcut that you want to the Windows desktop.
- Close the Unused Desktop Shortcuts dialog box.
