I’ve tried a lot of different software to make Windows more like a Mac (I was bored and just wanted to say I could haha) but the best option as far as installing a dock is by far RocketDock at http://rocketdock.com/

This thing is so fast, I barely notice its running (unlike Windows Sidebar which slows my computer to a halt sometimes :()

I owuld love to make my computer alot faster then what it is, but I dont want to make it look like a mac. Its cool how people mess around and do different things with their computers. I like the looks of windows xp and I will stick to it but thanks for this tip I am sure someone will want to do that.
