I have created both CD and Flash Drive.  Received notice in Win 7 update that my upgrade was ready to download and install. If I just use the CD instead of Win Update download will I receive an upgrade or a clean install.  Clean install requires a Product Key, does it or not.....?

Just install within Windows and it will upgrade don't boot on to the CD or Flash Drive just have windows running and install Win 10!

Can I reinstall Windows 10 on my computer after upgrading?

Yes. Once you’ve upgraded to Windows 10 using the free upgrade offer, you will be able to reinstall, including a clean install, on the same device. You won’t need a product key for re-activations on the same hardware. If you make a meaningful change to your hardware, you may need to contact customer support to help with activation. You’ll also be able to create your own installation media, like a USB drive or DVD, and use that to upgrade your device or reinstall after you’ve upgraded. To learn more, click here.
