If you’ve been wondering why your XP desktop icons have a background
color, you’ll be glad to know you can flip a checkbox and have them go
back to a normal transparent background.
See the two below:
To set the transparent background on the icons, we’ll need to open
System Properties in Control Panel (or right-click on My Computer and
select Properties).
In this dialog, click the Advanced tab, and then the Settings button under the Performance section.
Now scroll down to the button where you’ll find a checkbox for “Use
drop shadows for icon labels on the desktop”. Make sure you check this
box if you want transparent backgrounds on the icons.
Why this option isn’t just labeled “Enable Transparent Icons On the Desktop”, I just can’t say.
if checking it doesn’t fix your problem there is another step you must do. Follow this procedure:
Control Panel > Display > Desktop > Customize Desktop > Web > Uncheck everything here > OK > Apply
