Re: Unable to use Product Key to activate Windows 8 Professional Upgrade after a clean install
Did you try to go to Start and then in Search/Run type "slui 3" without quotes and then put in the key that you have purchased. Incase, that is not working for you then you can try to contact microsoft for the technical support. They will be able to activate the version of your Windows 8 very quickly without any trouble, since you have bought it genuinely. Get the number of their tech support from the below link:
