ISO files are commonly used for software installations, operating system images, or backup purposes. The good news? Windows 11 makes working with ISO files super simple.
In this comprehensive guide, I’ll show you what an ISO file is, why you might need it, and multiple ways to run (mount or open) an ISO file on Windows 11. By the end, you’ll be a pro at handling ISO files without needing third-party tools.
What is an ISO File?
Before jumping into the steps, let’s clarify what an ISO file actually is.
-
ISO file (or ISO image) is a single file that contains an exact copy of data from an optical disc like a CD, DVD, or Blu-ray.
-
It’s often used to distribute large programs, operating systems (like Windows), or software packages.
-
Instead of burning the ISO to a physical disc, you can mount it as a virtual drive on your PC.
Why Would You Need to Run an ISO File?
Here are a few common scenarios:
-
Installing an Operating System like Windows or Linux in a virtual machine.
-
Running a software installer packaged as an ISO.
-
Accessing game or application data without using a DVD or physical media.
-
Testing bootable media for troubleshooting or recovery.
Does Windows 11 Support ISO Files Natively?
Yes! Unlike older versions of Windows that required third-party tools, Windows 11 has built-in ISO mounting capabilities. This means you can open and use an ISO file without installing extra software.
