I am in the middle of exams so don't have time to fiddle with Windows 9 - might be interested in the future. I notice that all their special upgrade offers are expiring soon and want to know if it is worth it? I have the $14.99 upgrade offer and the free WMC add-on key as well. Questions: 1. Is it worth activating these special offers to have a full version of Win 8 before they expire? 2. Is there an easy way to secure these offers using a virtual machine or equivalent as I don't have time before Jan 31 to look at upgrading one of my machines? 3. I think that I have read on the forums here I can then back up my registration so I can do fresh install on a real machine once I am ready - is this correct? (and true for the $14.99 upgrade offer?) 4. Do I need a real key for an existing install of Windows (I think I have an XP key floating around somewhere) in order to upgrade? (All my others are running Daz Loader vers) Thanks in advance - I did look through the forums for some of this information but need an opinion as to whether or not this is worth the time.
