In simple words, for instance, if you had previously activated Windows 10 Home edition on a computer, when you run the setup of Windows 10, it automatically installs the Home edition without allowing you to select the edition of Windows 10. And when you are installing Windows 10 on a new PC or a PC without the embedded product key, it displays the prompt asking you to select the edition of Windows 10 that you would like to install. When you create a bootable USB of Windows 10 using the ISO and attempt to install Windows 10 from it, the setup of Windows 10 automatically checks your BIOS/UEFI for embedded product key (if available), and installs the right version based on its findings. Well, the fact is that the Windows 10 ISO that you download using Media Creation Tool includes both the Home as well as Pro editions, meaning Microsoft is no longer offering separate ISOs for Home and Pro editions.
