If you have to try this new function that Windows 8 will include, you only have to download Aura, and launch the application. A small icon will appear in the system tray and you will have to click with the right button and choose the options. You have access to three functions: that the windows use the dominating desktop color, from the window's icon and what's more, you can activate the option to use the dominating color from the active Internet Explorer 9 active tab.
Aura allows the Internet Explorer 9 window to change color depending on the page that you are visiting. For the changes to take place you'll have to close Aura completely and launch it once again.
Try the new feature of Aero for Windows 8 before anyone else. Download Aura and customize Windows' windows.
