Sorry about the unclear title, but I've been running Windows 10 on my machine since the free upgrade thing ages ago.
At that time I was running 8.1 Pro which was installed from a disc.
How do I go about doing a fresh reinstall of Windows? Do I install the old 8.1 Pro from my disc and then upgrade to Windows 10 again?
If so, how do I do this? Sorry about the novice questions, I've never done this before and want to do it properly.
Thanks.
 
Solution
Download Media Creation tool and install just windows 10, when it asks for a key just click on I don't have and it will activate automatically when you have internet.
