Users of both Windows XP and Windows Vista were writing to say that they could not validate their installations using WGA, and one user even said that his installation was invalidated by the service." The Microsoft WGA Forums are full of problem reports, and Microsoft WGA Program Manager Phil Liu has acknowledged that there is a problem, and that MS is investigating."
