|The key is not in/on the disk. The disk contains a formula to determine if the key you enter is valid. That way they can make all the disks the same. |
Sometimes the keys on OEM stickers aren't used as the actual installs are done en masse or from licensed distributers where the same key is used. The sticker just makes the installation legal even if its key isn't used. So you might try using keys from junked cases.
Or, if you're wanting to extract the key from a working system, there are utilities for that which I think Johnw linked to.
