  • Question

  • I have had to reinstall windows vista ultimate onto my computer, but when I try and activate it I get the message that the product key is already in use and that I will need toi buy another one. I have a genuine copy of Vista which always activated before n this machine.

    Can you explain how I can fix this problem?
