Before getting into the installation process, Microsoft has a few requisites that you need take note. First, a reliable internet connection; second, enough memory space on your PC to accommodate the ISO file; and third, a blank USB storage device or DVD with at least 4 gigabytes of free space for the media.

It is not recommended to clean install your PC since Windows will require a product key if so. Just ensure you meet all of the aforementioned requirements to avoid unnecessary circumstances.
