How to Mount and Unmount ISO Files in Windows 11
You can mount and unmount ISO files in Windows 11 by using the built-in File Explorer functionality.
An ISO file is a single archive file that contains all the data from an optical disc, like a CD or DVD. Mounting an ISO makes Windows 11 treat this file as if it were a physical disc inserted into a drive, creating a virtual disc drive.
This is incredibly handy for installing software, accessing game data, or retrieving backups without needing a physical disc or external burner. For instance, many older game installers are distributed as ISOs and can be run directly on Windows 11.
You don’t need any special third-party software to perform these actions; Windows 11 handles it natively.
Mount an ISO by opening File Explorer, selecting the ISO, and clicking Mount in the ribbon or context menu. Unmount it by right-clicking the virtual drive under This PC and selecting Eject.
What happens when you mount an ISO?
When you mount an ISO, Windows 11 creates a virtual drive in File Explorer. Your computer acts as if you just inserted a real disc into a drive. You can open, copy, or run files from this virtual location. When you are finished, you unmount the file to remove the virtual drive and free up system resources.

Can I mount an ISO file without third-party software?
Yes. Windows 11 has native support for ISO and IMG files. You do not need to download extra programs like WinRAR or Daemon Tools. Simply use the built-in File Explorer context menu or the PowerShell commands to mount your disk images directly within the operating system.
How do I burn an ISO to a disc after mounting?
Mounting an ISO does not burn it to a disc. To burn an ISO, right-click the file in File Explorer and select Burn disc image. You will need a blank writable CD or DVD inserted into your physical optical drive to complete this process successfully.
Does 🪟 Windows 11 support all ISO file types?
Windows 11 supports standard ISO and IMG files. However, some specialized or compressed disk images created by third-party software may not mount natively. If you encounter an error, the file might be corrupted or use a proprietary format that requires the original software to open.
