A Windows ISO file is a digital copy of a Windows installation disc. It often comes into play when users want to upgrade Windows or perform a clean install of Windows. 

This post focuses on the Windows 10 ISO download. Additionally, this article introduces how to create a Windows 10 bootable USB for your computer to boot from it.

How to download Windows 10 ISO from Microsoft

Before downloading Windows 10 ISO, we need to get a general idea of the system type: Windows 32-bit and Windows 64-bit systems.

64-bit Windows runs on modern 64-bit processors, which handle data in 64-bit chunks. This means they can process more data at once and use larger memory addresses ( e.g., Windows Home supports 128 GB, and Windows Pro/Enterprise supports up to 2 TB).

32-bit Windows runs on 32-bit processors, which handle data in 32-bit chunks, and it can address a maximum of 4 GB of RAM. Choose 32-bit Windows if your PC uses older hardware or RAM less than 4GB.
