How to verify Windows 11 ISO file (Disk Image)? | Check, is it original ISO file or not?

If you are planning to install or reinstall Windows 11 on your PC, then don't forget to verify the Integrity downloaded Windows disc image (ISO file) to avoid further errors or before making an Installation Media (bootable Pendrive).
In this blog post, I will show you, how to verify the Integrity of a Windows 11 ISO File?

How To Verify Integrity of Windows 11 ISO File?

We can verify the Integrity of a Windows 11 ISO file by computing the File Hash and then matching it with the original hash of the ISO file from Microsoft.
There is a Website named "List of files by Microsoft®", which listed all files from Microsoft with their File Hash. So, we will first compute the File hash of the downloaded Windows 11 ISO File and then, we will search that hash on this (List of files by Microsoft®) website.
We can compute File Hash easily by using a third-party app named 7-Zip and also using Windows PowerShell.

Compute Windows 11 ISO File Hash using 7-Zip

First of all, download and install 7-Zip. Or, if 7-Zip is already installed on your PC, then go ahead.
  • After installing, Open the location/folder/path of the downloaded Windows 11 ISO file.
  • Press and hold the Shift key on the keyboard, then right-click on ISO File and select "7-Zip" > "CRC SHA" > "SHA-256".
  • Then 7-zip will take some time to calculate File Hashes.
  • On the "Checksum information" window, double-click on SHA256 Row.
  • On the "SHA256" window, select the file hash and copy it.

Compute Windows 11 ISO File Hash using PowerShell

  • Open the location/folder/path of the downloaded Windows 11 ISO file.
  • On blank space, press Shift + Right-click and select Open PowerShell windows here.
  • Run the command according to system type: Get-FileHash ISOFileNameWithExtension
    Example: get-filehash Win11_22H2_English_x64v1.iso
    Here: Win11_22H2_English_x64v1.iso is ISO Filename.
    After some time, you will get the SHA256 value of that ISO file.
  • Then, select the file hash and copy it.

Match Windows 11 ISO File Hash on the "List of files by Microsoft®" website

  • Now, open the "List of files by Microsoft®" (files.rg-adguard.net) website.
  • On the website, Click on the Search button.
  • Paste the copied File Hash in the box and press Enter key.
  • If you found a result, then the ISO file is verified. Means it's original.
