The D: drive you are looking at is a partition created by Gateway that contains a mirror image of the exact software installed when your lap top left the factory. It is locked and protected from the Windows.
Should you ever suffer a sever infection, OS corruption, or just want to go back to factory default you can do so using the image on the D: partition. More information will be in the manuals that came with your lap top and can also be found on the Gateway site.
