What happens when you clean install, having previously upgraded to Pro
I upgraded from Win 7 Home Premium to Windows 10 Home through the usual method, but I wanted to clean install, so I used Microsofts tool for creating install media and made a windows home usb stick and clean installed from that. Activation worked automatically as expected and I've been using w10 ever since quite happily, though I really do think I'd prefer to have pro on the computer.
I see right now I can only upgrade to pro through the store app (as a side question will there ever be a retail pro pack available like there was for Windows 8? Only it tends to be cheaper than buying directly from Microsoft). If I upgrade to pro, what happens exactly if I ever need to reinstall the OS?
Do I just use the existing 10 home usb media I made and then download the pro pack again from the store (presumably it'd be free since I'd already bought it), or can I just create a new usb media with the pro version of 10 instead and install it that way?
