So once this downloads, is it going to be possible to write to a DVD for backup or does it need to stay on the hard drive?

I suppose MS supplying an *.iso file is asking too much.

Yes, the same download I linked to is a media creation tool, I put it on a USB stick. But if you have the free license from upgrading from 7 or 8, you need to run the upgrade first before doing a clean install from media.

The media creation tool can be used to upgrade your current PC to Windows 10 or to create a USB or DVD
