Can I download Windows 10 Pro ISO from Microsoft?
Before we tell you how to prepare Windows 10 Pro ISO, it’s important to note that Microsoft doesn’t offer Windows 10 Pro as a separate ISO. Instead, it offers a single ISO image containing both Home and Pro editions of Windows 10. But there is a way to make the ISO or bootable media automatically install only Windows 10 Pro edition.
While installing or reinstalling, the setup of Windows 10 automatically installs the right edition based on the key found in the BIOS or your previous Windows installation. If it doesn’t get any clue, it will ask you to select between Home and Professional.
