What Is ISO Image & What Can It Do for You?

An ISO image is a file containing operating system-related items. An ISO image is also known as an ISO file. It includes everything needed to boot up a computer or install the operating system (OS). Creating a Windows ISO image from the existing OS means making a system image file based on the current Windows OS.

It is vital to back up your operating system. Therefore, when your system crashes, you can quickly get it back to the state where the backup was taken. If the backup is an ISO image, you can enjoy some benefits compared with other image backup formats:

  • The ISO image is bootable, so you can use it to restore your computer when you have boot issues.
  • It is easy and convenient to deploy it to other computers.
  • It can be standalone from backup tools or cloud services.
  • You can run the ISO image on a virtual machine.

Free ISO Image Creator Software vs. Windows 10 Media Creation Tool

EaseUS Todo Backup and Windows Media Creation Tool can help you create an ISO image of your operating system. But there are stark differences between the two tools.

EaseUS Todo Backup Free is one of the best backup tools on the market. It is compatible with different versions of the Windows operating system, such as Windows 11/10/8/7. Besides, it is a multi-purpose backup utility. It supports multiple backup types, such as system backup, file backup, disk backup, and partition backup. It allows you to make a scheduled backup, full backup, differential backup, and incremental backup. Moreover, it provides 250G of free cloud storage space. Most importantly, it is easy to use because you can finish the backup process in a few simple clicks.

Windows 10 Media Creation Tool is a very top-rated utility. With it, you can easily upgrade Windows 10 to its latest version without a hassle. You can also use it to create a Windows 10 installation USB drive or DVD to perform a clean installation or repair a problematic computer. However, it only supports Windows 10/11; it cannot work on other versions of Windows systems. Unlike EaseUS Todo Backup, it is a dedicated tool for creating a Windows 10 ISO image, which means you cannot use it to do other things. Furthermore, compared with EaseUS Todo Backup, it has a more complex procedure for creating the Windows 10 ISO image.

In short, you can use EaseUS Todo Backup and Windows 10 Media Creation Tool to do a Windows 10 ISO Image.
