To use the Windows 10 Media Creation Tool, download Windows 10 Media Creation Tool from and run it. However, a valid Windows product key is required when directly installing Windows 10 for the first time on a device. No product key is required to download the Windows 10 ISO images, or to create DVD or USB media trough the Media Creation Tool. For those in need of an official Windows 10 ISO file, Microsoft has released a very simple tool named Media Creation Tool to allow you to download Windows 10 ISO images, or to create Windows 10 DVD disc or USB flash media, for clean installation.
