Windows Serial/License key which one do I use? - license and serial key for mount and blade

Hello everyone,
I have a Dell computer could delete and reinstall Windows XP. I have the recovery CD, but the problem is the serial number for Windows XP. I searched the internet to see how to find my serial number and more people are using this program called Magic Jelly Bean "Later, I noticed that in my case, I have a label stating that appears to be the key product, but the key out that the program will be different, that I use when you reinstall the operating system?
