Programmatically check whether Windows 7 is activated

Background: I am creating system images that will be loaded onto several workstations. Windows activation will occur after the images are loaded onto the workstation. These computers will not be connected to the Internet and will be activated over the phone.

Question: I would like to check programmatically if Windows 7 is activated or not, so that our software will not run if Windows 7 is not activated. Our software is written in C#.
