http://reviews.cnet.co.uk/software-a...ws-7-50009546/ this should help.
its pretty complex to uninstall windows 8. its just cause of the stupid start screen and all that nonsense. this should help you. keep windows 8 the boot time is amazing. and the resources it uses on the ram is better than 7
EDIT: for start8 if you want the unlock i think its against the forum rules to post things like that here. so you can inbox me.
