Before we proceed, we want to remind you that Windows 10 will receive security updates until 2028. Before support for this version of the operating system officially ends, it will therefore be advisable to upgrade to Windows 11.

Windows 10 ISO: what is it?

Windows 10 ISO is a digital image that contains all the files and folders needed to install Windows 10. It is a digital replica of a physical disk, allowing users to perform clean installations, upgrades or create bootable media for installation purposes. It provides an easy way to install or reinstall Windows 10 on your computer.

The ISO format ensures that the operating system remains intact and unmodified during the installation process. Whether you want to perform a clean installation, upgrade your existing system, or create a bootable USB drive, the Windows 10 ISO file is the option to choose. It is also important to know that although downloading and installing the operating system is free, to activate Windows 10 you need to purchase an original Windows 10 product key.

Mr Key Shop allows you to save up to 70% on the cost of your Windows license, allowing you to choose between the Home and Pro versions. A real boon, don’t you think so too? In addition, Windows 10 is compatible with the latest personal productivity software such as Office 2021 Professional Plus.

Why download a Windows 10 ISO file?

Downloading a Windows 10 ISO file offers several advantages.

Second, it is useful when you want to perform a clean installation or reinstall Windows 10 due to system problems.

Checking system requirements 

Before downloading and installing Windows 10, it is essential to ensure that your system meets the minimum requirements. Windows 10 generally requires a 1GHz processor, 2GB of RAM for 64-bit systems, 20GB of free disk space, and a DirectX 9-compatible graphics card.

Create a Bootable USB Drive of Windows 10 ISO

A bootable USB drive is invaluable when installing Windows 10 on a new system or upgrading an existing one. The process of creating a bootable USB drive from the downloaded Windows 10 ISO file is simple. You can use built-in tools such as Rufus or Windows Media Creation Tool to accomplish this task. To create a bootable USB drive with the Windows 10 ISO file, you will need a blank USB drive with at least 8GB of space.

Creating a Bootable USB Drive with Rufus

If you want to create a bootable USB drive using Rufus, follow these steps:

  • Insert the USB flash drive into your computer.
  • Download and install a reliable tool for creating bootable USB flash drives, such as Rufus.
  • Run Rufus and select your USB flash drive from the drop-down menu.
  • Click the “Select” button and choose the Windows 10 ISO file.
  • Set the partition scheme to “MBR” and the file system to “NTFS”.
  • Click “Start” to start the process and wait for completion.

Creating a Bootable USB Drive Using the Media Creation Tool

After downloading and starting the Media Creation Tool, a terms of use screen will appear and you will need to select “Accept”. Select “Create installation media (USB stick, DVD or ISO file) for another PC” and proceed to the next step.

At this point, choose the recommended options for your PC, or customize them by choosing a different language or architecture based on the PC on which you intend to install Windows 10. Choose the “USB flash drive” option and proceed to the next step. Select your USB flash drive from the list and continue.

The installer will download Windows 10 and write it to your USB flash drive. You will see a message saying “Your USB flash drive is ready” when finished. When the process is finished, close “Windows 10 Setup” and turn off your PC.

Burning the Windows 10 ISO to a DVD

If your computer has a DVD burner and you have a rewritable DVD available, you can burn the Windows 10 ISO to a DVD and install Windows 10 by booting from it.

Right-click the previously downloaded Windows ISO file and go to Properties (under the General tab), then select Edit > Windows Explorer > Apply. Next, right-click on the Windows ISO file and select “Burn Disk Image”. “Burn Windows disk image” will be opened, asking you which drive you want to use. When you are ready, start the “Burn” process.

When it is finished, you will have a bootable DVD that you can use to install Microsoft Windows. You can use other software to burn your ISO, but the built-in software is fairly easy to use. Once the burning is complete, you will need to boot your PC (or another PC) from the DVD.
