To get a fresh view of your Windows 7 system, change the Aero Theme. The Xbox 360 lets you change its Dashboard theme too.
Here I’m using the latest Xbox dashboard update. Select Social then your Xbox Live avatar.
On the next screen select Change Theme.
Highlight the Theme you want to use. The theme is displayed as you highlight each one.
Here I’m selecting The Elder Scrolls V: Skyrim Theme that I purchased from the Xbox Marketplace.
That’s it. It’s cool to change your Xbox dashboard theme once in a while to for a fresh view.
