I came across an excellent Windows Theme - Rainmeter. If interested download rainmeter v2.0 or the beta, grab their themes or go to customize.org and grab more themes there. Then use Rainbrowser to add what gagets you want on your desktop. Avoid DeviantART themes according to Rainmeter warnings that some of the images from DeviantArt contain viruses. Ive tried system hoggers like WinStep extreme and Window blinds they all just slow down your pc. Rainmeter is very light on the PC resources.
