If you are reading this post, then you are having issues with your Windows 10 ISO files. If you are using Windows Explorer to mount the file or a third party application, read this troubleshooting guide to learn how you can fix your Windows 10 .ISO file.
One of the main reasons why you’re getting the “file has been corrupted” error is the fact that you previously installed a third party ISO application or your Windows 10 computer. Another possible explanation is that certain system files have been corrupted since your last used Windows Explorer.

4. Download the ISO file again
Go again to Microsoft’s website where you downloaded the .ISO file and redo the process. Sometimes the download process can get interrupted at one point or another resulting in an unfinished download.
Yes, as simple as this solution may seem, quite a few users confirmed they managed to fix the problem by relaunching the ISO download process.
5. Use a different ISO mounting software
Well, if the problem persists, try using another ISO mounting software. The current tool may fail to work due to incompatibility issues, a specific technical issue that hasn’t been patched yet, etc.
For more information on the best ISO mounting software to use, check out this guide. We highly recommend Power ISO. This program comes with the following features:
- Process ISO / BIN image files, make bootable CD image file. PowerISO supports almost all CD/DVD image file formats
- Mount image file with internal virtual drive, and then use the file without extracting it
- Compress files and folders to a compressed archive. PowerISO will scan and optimize the files during compression, and thus can have better compression ratio and faster compression speed
- Split the archive into multiple volumes
- Protect the archive with a password
- Use the archive directly without decompressing. PowerISO virtual drive can mount the archive directly.
6. Use DISM with RestoreHealth
The Deployment Image Servicing and Management, also known as DIS is a tool that helps your service and prepares Windows images.
You can use the DISM command to scan the Windows image for any corruption issues and replace missing or corrupted file. Here are the steps to follow:
- Go to Start > type cmd > right click on Command Prompt > launch the tool as Administrator
- Now, you’re going to run three different commands to repair Windows image corruption issues:
- DISM /Online /Cleanup-Image /CheckHealth
- DISM /Online /Cleanup-Image /ScanHealth
- DISM /Online /Cleanup-Image /RestoreHealth
Hit Enter after each command. Wait until the current command has completed the scanning process before entering the next one. Keep in mind that the whole process might sometimes take up to 30 minutes.
And you are done. If you followed the steps above, your .ISO file mounting issues should be history now. If you do have other questions or you ran into any issues while following the steps listed in this tutorial, let us know in the comments below.
