is there any way to tell what type of product key a person gives you? for example, a lot of times i'll need to format and reinstall windows on a computer where all the customer gives me is a product key and tells me the have "Windows XP". i am looking for a way to tell which version, or channel, i guess they call it it was obtained through. if this makes any sense to anyone i would really appreciate some help. Thanks! -Voltaic
