If your Windows XP system has icons on the desktop which absolutely refuse to show drop shadows, despite having changed the effects setting in the System control panel to use them, here’s what you need to do to fix it.
- Go to the Display control panel (right-click on the desktop and go to Properties)
- Go to the Desktop tab
- Click on the Customize Desktop button at the bottom
- Click on the Web tab
- Uncheck the box “Lock desktop items”
- Hit every OK button you just pulled up until all the control panel stuff is closed.
That’s all there is to it!
