This is the standard method for Windows users to generate a bootable ISO.
The ISO download does not include a license. You will need a valid Windows 10 Pro product key to activate the software after installation. If you previously had Windows 10 Pro activated on that hardware, it should reactivate automatically via a digital license.
Use a utility like Rufus or the Media Creation Tool itself. Process: Open Rufus and select your USB drive. Select the Windows 10 32-bit ISO you just downloaded.
Advanced control over OS settings and updates.
Ability to connect to your machine from another device.
