This isnt really a huge thing but a few weeks ago i tried stupidly to get windows 8 pro with windows media centre for free by getting a product key from the internet. I really want to undo all of this so that is why i want to reset my laptop but i am scared that it will ask for a product key which i don't have as it was already built in when i bought it. I want to go back to the normal windows 8 pro by reseting but i was wondering if it would just make me keep it as windows 8 pro with windows media centre but if it doesn't i will be stuck as i wont have a key for windows 8 pro... Any help? Thanks
