How to verify Windows 11 ISO file authenticity using PowerShell

To check the Windows 11 ISO hash value, open PowerShell (admin), run the “Get-FileHash C:\PATH\TO\WINDOWS11.ISO” command, and compare the results with the official list of hash values.
This list includes the latest hash codes to confirm the authenticity of Windows 11 25H2.

UPDATED 10/3/2025: When you download the Windows 11 ISO file, you can verify its data integrity and authenticity to ensure it has not been corrupted, tampered with, or altered. You can do this with a PowerShell command and compare the result with the hash published by Microsoft.

A hash is a numeric value that uniquely identifies data calculated using the original data, in this case, the contents of the ISO file. If the contents change in any way when verifying the file, the hash number will change, indicating that the file isn’t original.

If the Windows 11 ISO file fails to create a USB flash drive and the hash number doesn’t match the original value, you may need to download the file again, as trying to use it may prevent you from completing the installation successfully.

In this guide, I will walk you through the steps to verify whether an ISO installation image is original, corrupted, or altered.

Check Windows 11 ISO file hash with PowerShell

To verify a Windows 11 ISO file download, use these steps:

Open Start.
Search for PowerShell, right-click the top result, and select the Run as administrator option.
Type the following command to verify the ISO file and press Enter:
```
Get-FileHash C:\PATH\TO\Win11_25H2_English_x64.iso
```
In the command, update the path with the location and the name of the Windows 11 ISO file.
Confirm the SHA256 (hash) output with the information below.

Quick tip: You can copy the output and use the “Ctrl + F” shortcut to find the hash in the list below.

Once you complete the steps, you can confirm whether the file has been corrupted, tampered with, or altered from the original.

It’s important to note that hash values will change depending on the ISO version. If you download the image file from a source other than Microsoft, the hash value will likely not match.

FAQs about the ISO file hash for Windows 11 25H2

Here’s a list of frequently asked questions (FAQs) and answers regarding the ISO file hash.

Why should I verify the Windows 11 ISO file?

You want to verify the ISO file to ensure it hasn’t been corrupted, tampered with, or altered. A mismatched hash means the ISO is unsafe.

Which hash algorithm does Microsoft use for ISO verification?

Microsoft publishes SHA256 hash values for official ISO files.

What happens if the hash doesn’t match?

If there’s a mismatch in the hash check, delete the ISO and redownload it from Microsoft’s official site. Don’t attempt installation.

Can I use a tool other than PowerShell?

Yes. Third-party tools like HashCalc or QuickHash can verify SHA256 values, but PowerShell is built in and reliable.

Do hash values change with each ISO version?

Yes. Every ISO release has a unique SHA256 hash. Always use the latest list from Microsoft.

Where can I find Microsoft’s official ISO hash values?

They’re published on the official Microsoft download page or documentation. This guide includes the current list for Windows 11 25H2.
