Windows Activator App

I just installed Windows XP Pro on a new computer, now it wont let me log into my account unless I activate Windows. So I used this kind of app before I just cant find it. You type in the Windows XP serial you used and then it generates a confirmation code that you type in when your activating it by telephone.
Does anyone know where I can get one of these apps?

Answer #2
