Activations Code For Mount And Blade How Do I Find My Windows Xp Activation Code In Safe Mode?

How do I find my windows xp activation code in safe mode? - activations code for mount and blade

My hard drive is really bad. So I need is to format (I hope it works).

But after several moves, I can not find the CD Windows XP activation code. I run only Windows in Safe Mode. Is there anyway to find in the registry?
