The Windows Vista box opens with a swing-out section that holds your DVD and manuals. The box has two security seals that need to be cut or removed before it can be opened.
On the top of the box, cut along the grooves on either side of the Microsoft Certificate of Authenticity label.
Peel the red tabbed label off the front of the box and discard.
Holding the box with the Windows logo facing you, grasp the red tab on the top of the box, and pull it to the right to open the box as shown here.
