so you mean if i create a custom image that comes from the fresh install and install it to many laptops that has a same unit, model and specs is not illegal? then after i install the image i restart the laptops and go to the administrator and use the sysprep and check the product key if it is match on in the embedded key from the motherboard then i check the drivers as well if it is all installed and after that i click generalize onthe sysprep and shutdown. thats all.
