i've installed a copy of windows xp home edition that i borrowed from a friend, because my computer decided to format it self thus wiping everything off including my OS. the installation went alright, i entered the product key from my hardrive but now its asking for a product key to activate windows ive tried my key again, but no luck. Any ideas or solutions much appreicated... especialy since it says ive only got 26 days left! lol. thanks! =]
