Notes on using the media creation tool by Microsoft:

The media creation tool is a free application by Microsoft. This free program allows for the creation of an installation medium for Windows 8.1 Professional, Windows 10 Home and Windows 10 Professional as well as certain other Windows versions. The media creation tool runs on both 32 and 64-bit systems, and installation media can be created for Windows installations on both 32 and 64-bit computers.

Windows can be installed as a new installation, not as an upgrade, on any computer that fulfills the minimum hardware requirements for the respective Windows version, regardless of the operating system currently in use, if any.

The installation medium can only be created on computers running a working installation of Windows 7, Windows 8 / 8.1 or Windows 10.
