i bought a laptop and it was a display ideal and never got any goods key for Windows 7. What should i execute?

Take it back. Even if it was a demo mannequin, you should have gotten all the installation CD's that came with it. If they can't emanate them, next I would ask for my money back. You might not need them nowadays, but the time will come when you might have to instal something, and without those disks you can't. Just goes to be, good deals aren't always good deals.
