Hi guys out there, I really do hope that someone could assist me in getting my Windows Vista Ultimate activated. Everything is fine except that it is telling me to activate my Vista within 30 days. I'm currently using a Dell Dimension 5150 loaded with Windows XP Home. I have tried all the keys given here and non of them works and I even tried it with a Dell Recovery CD to recover it into Vista Business, still cant work. So any experts out there, please help me! Thanks!
