Sorry for the question if is quite simple but I am unsure. Currently I am running Windows 7 Ultimate yet my copy can't be validated as I have no key. If I was to purchase a copy of Windows 10 would I be able to keep my files during the upgrade or would a fresh install be required?
Hello Caligula, and welcome to Ten Forums. :)
Can I reinstall Windows 10 on my computer after upgrading with free upgrade?
Once you’ve upgraded to Windows 10 using the free upgrade offer or Media Creation Tool on an activated Windows 7 or 8.1 PC, 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.
If you purchase a Windows 10 that is the same edition you have install, then you'll be able to change the key for your installed Windows to the key that you purchased to activate it.

Your files won't be deleted, as you'll be able to enter the key after you did the upgrade process.
