I've just found a great little application for Windows PC's, (32 & 64 bit too!), it's called RocketDock http://rocketdock.com/
It gives you a Program Dock very similar to a Mac, so you can clear your desktop of icons all over the place, and put them all on the Rocket Dock. There are hundreds of new icons that you can download from the same site, to change the appearance of the dock. I am really loving it! It's all free too!
