How can I get a Windows XP key to activate Windows? - windows xp key

I installed Windows XP on my laptop back on and said that it is not activated. I just found out that there is now installed only on a computer. I need a valid key from Windows XP to activate them. Anyone know where I purchuse a cheap white is key, because I have an extra $ 100 for something that they have already paid to pay. Thanks
