How to Mount an ISO in Windows 10: Every Method That Works

To mount an ISO in Windows 10, double-click the .iso file in File Explorer, or right-click it and choose Mount. No burning to a blank DVD first, no extra program. Windows has handled disc images by itself since Windows 8.

Windows creates a virtual DVD drive with its own letter in This PC. We open, copy and run files from it as if a real disc were inserted.

• Double-click the .iso file.
• Right-click it, then Mount.
• The File Explorer ribbon.
• PowerShell, for scripts and Server Core.

No extra software is needed. The feature has been built in since Windows 8, and it works the same on Windows 11.

Below is every method we use, plus the fixes for the moments when the Mount option vanishes or an image refuses to open.

What an ISO file is

A single-file copy of an entire CD, DVD or Blu-ray. The name comes from the ISO 9660 disc file system standard. Most modern images use UDF as well.

The file holds every file and folder of the disc, plus its structure. A mounted image gives the same content as the disc. It’s served from your SSD, not from a spinning drive.

Virtual mounting makes Windows believe an optical drive is connected. Reads come from your disk. An installer that crawled off a DVD finishes far quicker.

A typical use: some ancient software exists only on disc. Nobody wants to hunt for a dusty external drive on every PC. One image, made once, installs it on four machines.

How to mount an ISO in Windows 10

There are three point-and-click ways. Each one assigns the next free drive letter and opens the virtual drive. None needs anything beyond File Explorer.

1. Open File Explorer with Win + E and browse to the .iso file.
2. Double-click it.
3. Windows mounts the image and opens the new drive.

The quickest of the four. It normally works out of the box. It only stops working when Windows Explorer is no longer the default app for .iso files.

Right-click and choose Mount

1. Right-click the ISO file.
2. Click Mount.

In Windows 11 the entry sits in the first context menu. If it doesn’t, use Show more options.

The result is the same. This route works even when another program has grabbed the double-click.

The File Explorer ribbon

1. Select the ISO once.
2. Open the Manage tab under Disc Image Tools, at the top of the window.
3. Click Mount.

Once mounted, the drive appears under This PC with a DVD icon. Browse, copy, run setup.exe. Everything behaves as if a real disc were inserted.

You can’t save changes back into an image. It only gets read.

No admin rights needed for an ISO on Windows 10 or 11. Standard users can mount one. Windows Server is stricter: there only an administrator can mount or eject an ISO.

Ejecting a mounted ISO in Windows 10

Open This PC, right-click the virtual drive and choose Eject. The drive letter disappears and the file is released. You can move or delete it then.

Eject fails? A program still has a file open on that drive. Close it and try again.

As a rule, images also dismount by themselves at a restart. That surprises people who expect the drive to come back after a reboot.

For a stubborn drive, use PowerShell or reboot. Disk Management can show the drive. We wouldn’t count on it for a reliable eject.

Mount an ISO in Windows 10 with PowerShell

Two cmdlets, both built into Windows 10 and 11. One mounts, the other removes. This is the method for scripts, remote sessions and Server Core.

Mount-DiskImage -ImagePath "C:\ISO\Win10_22H2_English_x64.iso"
(Get-DiskImage -ImagePath "C:\ISO\Win10_22H2_English_x64.iso" | Get-Volume).DriveLetter
Dismount-DiskImage -ImagePath "C:\ISO\Win10_22H2_English_x64.iso"

Another way to get the letter: add -PassThru to the mount cmdlet and pipe the result to Get-Volume.

A small script can mount an image, run the installer silently from the returned drive letter, then dismount. Across a batch of new laptops that saves hours.

The same cmdlets also mount VHD and VHDX virtual disks.

Mount an ISO in Windows 10 from the command line

Command Prompt has no mount command of its own. No problem. It can hand the job to PowerShell in one line:

powershell -NoProfile -Command "Mount-DiskImage -ImagePath 'C:\ISO\file.iso'"

And the reverse, once you’re done:

powershell -NoProfile -Command "Dismount-DiskImage -ImagePath 'C:\ISO\file.iso'"

Handy in old batch files. The full path matters here, a relative one gets refused.

A fixed drive letter

Windows picks the next free letter. That moves around as USB sticks come and go. To pin it, use Disk Management.

1. Right-click Start and open Disk Management.
2. Right-click the CD-ROM entry of your mounted image and choose Change Drive Letter and Paths.
3. Click Change, choose a letter and confirm with OK.

The setting lasts until you eject the image. We’d pick M for mounted images. Scripts and shortcuts then never break.

When the Mount option is missing in Windows 10

Usually a third-party tool became the default app for .iso files. 7-Zip, WinRAR and PowerISO all do that. Set Windows Explorer back as the default, and both the double-click and the right-click entry return.

1. Right-click the image and choose Open with, then Choose another app.
2. Select Windows Explorer and tick “Always use this app to open .iso files”. Click OK.
3. Or go to Settings, Apps, Default apps, Choose default apps by file type. Find .iso and pick Windows Explorer.

Less often the image sits on a network share, or a system file is damaged.

Explorer is already the default, and the entry still doesn’t appear? Copy the image to a local folder first. Then repair system files from an admin prompt:

sfc /scannow

Fixing “Couldn’t mount file” and other errors

Most failures fall into four groups.

• A damaged or incomplete download.
• A file flagged as sparse.
• Security software blocking the virtual drive.
• An image that isn’t really ISO 9660 or UDF.

The sparse flag gets cleared with the first line below. The second line prints the hash, to compare with the value the publisher lists.

fsutil sparse setflag "C:\ISO\file.iso" 0
Get-FileHash C:\ISO\file.iso -Algorithm SHA256

One more culprit to rule out early. Antivirus software can block or quarantine the virtual drive when the installer inside looks suspicious. We’d check its log before anything else.

Installing Windows from a mounted image

Yes for an in-place upgrade or repair. No for a clean install.

1. Mount a Windows image. For Windows 10, only from Microsoft’s Windows 10 download page.
2. Run setup.exe from the virtual drive.
3. Choose to keep files and apps.

That reinstalls or upgrades Windows over itself. Files, apps and most settings stay where they were.

Wiping the disk and installing fresh takes a boot from a USB stick through the BIOS or a DVD made from that image.

For a fresh start, follow our guide to create a bootable Windows 10 USB, and then the clean install walkthrough. Office images are on our ISO download page.

A few habits that help with installs:

• Verify the hash before installing an operating system. Corruption mid-setup ruins your day.
• Multi-disc software. Eject one image and mount the next when the installer asks. Keep the set in one folder, with clear names.
• Very old software. It sometimes checks the disc volume label. The mounted image keeps the original label, so this generally works.

Third-party tools in 2026

For plain ISO files you don’t need any. Windows 10 and 11 mount them natively.

Third-party tools still help in three cases. Formats Windows can’t open, such as BIN/CUE, NRG or MDF/MDS. Several drives with fixed settings. Or editing the image.

Windows 10 can’t create an ISO from a disc by itself. That’s why ImgBurn stays in the toolkit. It rescues important CDs before they stop reading.

Organizing an image library

• One folder per product family, with a subfolder per version.
• File names with product, version, edition, language and architecture.
• A short readme beside images with special install notes.
• Hash files for anything used to install an operating system.

A file name in that style looks like this:

Office_LTSC_2024_ProPlus_en-US_x64.iso

That way any image can be checked before use and found in seconds, even years later. Sorting by name then groups every version of a product together.

How businesses use it

• As installation sources on a network share.
• As test media for checking software compatibility.
• As preserved copies of legacy disc-based applications.
• As recovery media that’s always one double-click away.

All of this replaces physical disc libraries that scratch and get lost.

Network shares deserve one warning. If mounting over the network is slow or refused, copy the image locally.

For upgrades, a mounted Windows 11 image from the Windows 11 Media Creation Tool is also the quickest route on PCs that qualify. Our Windows 11 vs Windows 10 comparison helps decide whether it’s time.

Still working in 2026

The feature keeps working, on Windows 10 and on Windows 11.

If you reinstall Windows 10 from an image, keep your Windows 10 product key ready. Our Windows 10 activation guide covers the step after setup.

Mount-DiskImage options for an ISO in Windows 10

The PowerShell cmdlet has a few switches that the right-click menu doesn’t. They matter in scripts.

Mounting the same file twice? The cmdlet refuses. The error reads “The process cannot access the file because it is being used by another process”. Dismount first, then mount again.

Rights differ too. An ISO mounts without admin rights on Windows 10. A VHD or VHDX needs an elevated console. On Windows Server, even an ISO needs an administrator.

A short script for a mount, a silent install and a clean exit:

$img = Mount-DiskImage -ImagePath "C:\ISO\tool.iso" -PassThru
$letter = ($img | Get-Volume).DriveLetter
Start-Process "$($letter):\setup.exe" -ArgumentList "/quiet" -Wait
Dismount-DiskImage -ImagePath "C:\ISO\tool.iso"

The silent switch differs from installer to installer. Check the vendor’s notes for the right one.

Windows versions where these ISO mount steps work

Menus look slightly different between versions. The commands and the results are the same on each one.
