I was one that was able to upgrade for free from Windows 7. Everything had worked just fine, yet my computer never ran nearly as good after the 1607 update, despite fixes.
With my upgrade, am I able to Clean Install without having to install Windows 7 first then upgrade to Windows 10? If so, do I need any information PRIOR TO starting this process?
Yes. You have a Digital Licence for Windows 10 tied to your PC's hardware and stored on Microsoft's activation servers. If asked for a key, click 'I don't have one'. You don't need it - after a clean install the licence will be checked and automatically activate the new install.
NB: you must install the same edition, Home or Pro as you had before.
Yes you can, once your Windows 10 was activated, it is forever on that ONE computer, unless you change your motherboard. Here is a tutorial to give you instructions on how to clean install.
