Currently i have windows 10 enterprise and it says its not activated. If i bought this key - http://www.ebay.co.uk/itm/Windows-10-Pro-Professional-1-License-key-Digitally-Delivered-1Hr-/151909373788?hash=item235e81175c:g:0a4AAOSwhkRWcFQG would it stop the popup and successfully activate windows 10 pro? (also i understand this is ebay but they have sold over 170 and they accept returns and it is covered with ebays money back guarantee.)
