Windows and Office Genuine ISO Verifier is a free program for Microsoft Windows operating systems that enables you to verify the authenticity of Windows or Office ISO images.

You may want to verify ISO images before you use the image to install a version of Microsoft Windows or Office.

While you could say that this should not really be an issue if you have downloaded the ISO from Microsoft, it is still better to be safe than sorry.

This is true especially if the ISO came from a third-party source. Making sure that the ISO image is genuine ensures that the image has not been tampered with.

A basic example are manipulated ISO images that will install the operating system or Office just fine, but add malicious programs to the mix on top of that.

Note: The application requires the Microsoft .NET Framework 4.0 Client Profile. It is compatible with all versions of Microsoft Windows from Windows XP to the very latest version.

Windows and Office Genuine ISO Verifier is an easy to use program. Simply extract the archive after you have downloaded the application.

The interface lists just a couple of options that are easy to understand.

Click on the three dots next to input file to select an ISO image stored on the local device that you want the program to check.

Click on the verify button afterwards, and wait for the program to compute the SHA-1 (sometimes also MD5) hash value. Once done, that value gets compared to the list of hashes the application ships with.

If a match is found, you get a green genuine status followed by the source the ISO image came from. If the has does not match, you get a red "not genuine" status instead.

Windows and Office Genuine ISO Verifier may also list the file name that the ISO image was offered as under "results of verification".

The application supports a wide variety of Windows and Office versions. Basically, any client and server version of Windows is supported, and as are all Office releases from Office 95 to Office 2016.

Closing Words

Windows and Office Genuine ISO Verifier is an easy to use program to authentication Windows or Office ISO images. While you need to trust the author of the application first and foremost, as all checks are based on the hash database the program ships with, all ISO images that I checked during tests verified correctly.

It is certainly possible to verify the hashes of downloaded ISO images manually, but that requires that you have a base hash that you can compare the computed results to.

All in all a handy program provided that it will be updated regularly by its author.

Now You: do you verify downloaded programs or ISO images?

    It doesn’t seem to work correctly with latest ISOs from Media Creation Tool for Windows 10 (AU Update included). I have both 32 and 64-bit version of latest Windows 10 ISO from MCT and it shows them as NOT GENUINE. Weird :/

    Yes, verification is necessity. On Ubuntu is no need to download external application or frameworks for this. Simply type in terminal “sha1sum [checked file or file with hashes]” or even better with OpenPGP “gpg –verify [signature file]”.

      You don’t need third party apps in Windows, either. Just use “certutil -hashfile [filename] sha1” in command prompt.

    How nice of Microsoft to provide free tools for us to check if the ISO that came with the DMS hacks are good or not.

      Where did these data come from, that this is a Microsoft Tool?

      Look again.

      Microsoft did not create it.

      This code could actually infect your valid Windows ISO and then tell you it is valid.
