Hi, Have recently formatted my hard drive and reinstalled Win XP. It asks for my serial key. I have a genuine copy of Win XP with serial key. Have typed in the serial key but for some reason my serial key is not accepted. I have 2 days left to activate my copy of Win XP and can't understand why my serial key is not accepted even though I have a genuine serial key. Any ideas as to what I can do?1 person needs an answerI do too
