If you would like your desktop Icons to have no text underneath then try this tweak:

Right click the icon and select "Rename"

Now hold the "Alt" key and type "255" and hit Enter

NOTE : It may only work with the keypad numbers and not the number keys on top of the keyboard. You also can get special character in this way such as "™" and other. Just refer to the
"character map" ( start>all program>accessories>system tools>character map) for more special character shortcut.
