Suppose you can’t copy this CD and after a while it get’s scratched, bent, broken, … normally you should get it exchanged with a new one, paying only fabrication costs of the CD (1 $). This is because you already paid royalties on the original CD and don’t have to pay it twice. The same goes for software, only no-one knows/tries it. So if you have an original M$ CD and it breaks, go to your local store and they should provide you with a new CD. Of course they won’t do it because nobody does, but when you go to court, I bet you’ll win.
