WindowBlinds is my favorite

I have tried many Desktop Enhancing Softwares but I liked WindowBlinds the most.

When you install it, you will find that it already has a few cool skins like Simple Alpha,Airframe,Aura,Blackcomb and Dogmax4.

You can also download free skins from http://www.windowblinds.net/

If you have less than 256 MB RAM, I suggest that you don’t use WindowBlinds as it will reduce Windows overall performance.
