That all looks photoshop'd i just don't see anyone creating something that advance of a shell this early for Windows 7.
Some of it I can see it downloaded, for example....
The circle bar in the top right looks like circle dock just set up in the corner of the screen.
The taskbar was put in the top right. Other than that I don't see much else being legit. If it is hats off to the author cause that is looking good.
