As Windows users, you actually have a lot of options for implementing a dock on your Windows desktop as you can see via this post on MakeUseOf, which highlights their six favorite programs. However, one of my personal favs for implementing a dock is ObjectDock, a program which allows you to add a skinnable dock to your desktop. The newest version, which has a redesigned UI, has been sped up and now includes some useful utilities too, like the weather docklet. But it's Vista users who really luck out as we get live thumbnail previews as well as minimize and restore effects thanks to the new Windows Vista desktop graphics engine which provides hardware acceleration features. There's a free version available as well as a Plus! version for $19.95 which offers some additional effects and features.
