The design team behind the shock family (iconshock, webdesignshock and themeshock) have created a complete set of GUI elements inspired by the new windows 8 interface, called Metro.
It was made purely in Photoshop using vector shapes, so it will be easily adaptable to your design changes.
It contains more than 100 GUI elements for windows 8 (PSD)
