Product key is already in use. RRS feed

  • Question

  • Hi,

    I've got Vista basic, which I installed onto a new harddrive in  my computer that I was rebuilding, and activated it with no problems.

    Unfortionalty that computer wasn't working to well with Vista, so I brought a new one, and put my Vista basic onto that.

    Now when trying to activate Vista it says my product key is already in use. What do I do? How do I get if off my old computer, which has gone back to XP, and use it on the new one?
