The XP Icon Raider is a simple tool that lets you replace the existing Windows 95, 98, or ME shell icons with the icons Windows XP uses.

One click and you're done. This utility will replace all icon settings to point to the new library, it doesn't harm those you have now. If you have any special icons setup for the recycle bin, etc. just re-enable them as you normally would if you decide not to use those supplied. Includes a full revert (undo) in 3 areas just in case you do not like the new icons.
