GOt a copy of XP Home from work. I installed using the original keys that came with it so i could install on my computer at home. I want to change the key so i can activate it. I have been using the Blue List keygen and have prodcued many valid keys as it says but when entered XP says they are incorrect. I do have setting on XP home to produce those keys. I even tried the Devils own key (FCKGW-RHQQ2-YXRKT-8TGGW-2B7Q8) and that doesnt even work. Now XP says that the grace period has expired please activate. I can still move aroud thru XP eventhough it says its expired. Will accessing the internet with XP be ok or will it call home? thanks
