This is probably a stupid question but i'm going to building a pc soon and with cyber monday i'd like to see if i can get a copy of windows 8.1 but the problem is i can only find it in cd form and my new pc won't have an optical drive so i'd like to get it on a usb but i have no clue how so if someone could explain how to install it and link me to where i can buy it to put on a usb it would be much appreciated.
you can get it free, just gp to youtube and search how to activate windows 8 free and during the installation if windows asks for product key just click next
