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.

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.

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