I tried this but it doesn't work with my Win 7 key.In Windows 10 go to the System Page. Then click change product key down to the right of the Windows Activation section. The try typing in your 7 Ultimate key. If its rejected you will be no worse for wear. It will just stay on 10 Home. If it's accepted it will upgrade with no install media required. Once its upgraded it will reboot to 10 Pro. Then go back in and make sure its activated. I've done this to go from 10 Pro to 10 Education and from 10 Pro to 10 Enterprise. I entered Windows 10 keys though. Once you go up, you can't go back down without reinstalling, just so you know. All system restore points are erased when you upgrade. I don't think there is an clickable Add Features option anymore, not that I've seen like in Windows 8.
