And again no. If you want a clean install your current license does not include use or access to a free copy of the full retail OS that you have to pay for.
There are many folk that don't understand this so be sure to take time to consider how deep an undertaking it is to install Windows from scratch. If it was easy, you'd have done it but the license is just the first hurdle.
BUT HEY!!! What is this crapware? One owner removed some control apps and then screamed about no WiFi. Well they uninstalled the app that turns it on. Do you know what you are doing?
I recently bought Lenovo IdeaTab Lynx K3011 tablet that came with Windows 8 Pro preinstalled on it. Although it didn't have too much crapware, I'd prefer to have a fresh copy of Windows without Norton deep-seated in it, etc. Is there any way I can download Windows 8 from Microsoft and reuse whatever is needed for registration?
