Hello to evry one

i'm new to knoppix and linux but i tried it and i like it a lot.

now i have this problem.
the windows computer of a frend of my crased but thanks to knoppix i'am able to start it whit the cd .
i saved the data he needed.
But he is not able to find the serial number of the windows cd so he can't install it .

So my question is it posible to read the serial number that is writen in the register of windows from knoppix .


if so can some one tel me how.

Thank for your time and sorry form my bad english.
