A 4 GB USB flash drive or a DVD disk for the creation of an OS file.

Enough storage space should be available on your computer which is used to download the ISO.

Microsoft has made a checklist of things required before you can actually download the free ISO image. The news which will surprise most of the readers is you don’t need a product key to download a Windows 10 ISO from Microsoft but a genuine Product key will be required for activating Windows 10 after downloading and installation process is completed. With the help of an ISO image, one can also create a bootable USB flash drive or a bootable DVD that can serve as the installation source. But there are some people who would require an official Windows 10 ISO image to manually install or reinstall the OS on formatted systems. In July 2015, Microsoft started distributing Windows 10 to the registered PCs almost 24 hours before the official launch of the operating system.

We know most of the users have installed Microsoft Windows 10 on their systems with the help of a free upgrade provided by Microsoft. Finally, you can download the Windows 10 ISO file without a product key directly for free from the official site. According to Satya Nadella, CEO Microsoft, Windows 10 marks a new beginning for the world of personal computing.

This time, Microsoft has left no stone unturned in providing the options for installing Windows 10 and has covered all the bases. Microsoft Windows 10 is now used on most computers/laptops/notebooks as the primary operating system, thanks to the free upgrade provided by Microsoft.
