Windows 10 upgrade is full clean installation ?
I had windows 8.1 pro original dvd installed on my system.
Then I upgraded free to windows 10.
Now I want to make a new clean installation of windows 10 without keeping old files and directories and apps on c:\
So I downloaded the Microsoft windows 10 media creation tool.
Running it and I selected not to upgrade but : Create installation media for another PC
Now it's downloading the windows 10 and in the end I will create a bootable installation on my flash drive disk on key.
My question is if I will need a serial number/key when installing the windows 10 ?
My goal is to install a new clean windows 10 even with formatting c:\ or even delete and create new partition on c:\ but the idea is to install new clean windows 10.
