Windows 7 ISO Verifier

One problem that many users face who download a build of Windows 7 from unofficial sources is that they have to verify that the ISO has not been tampered with. In other words: That the hash of the ISO turns out to be exactly the same as that of the version that was distributed by Microsoft directly. Some users who release Windows 7 builds on the Internet post the hash values of these images along with the download to make it convenient for users. Problem that can arise here is that downloaders need to trust the uploader.

The Windows 7 ISO Verifier has been created by Long Zheng and Sven Groot. It basically allows users to verify a Windows 7 ISO image without knowing the hash of it or the has that it is supposed to have. Iso images can simply be dropped onto the exe after download. Another option is to execute the Windows 7 ISO Verifier and pick the exe this way.

The program will then calculate the hash of the local ISO image and compare it with a database of hashes on the Internet that gets constantly updated. The process is fast and tells the user right away if the ISO is verified or not. It can obviously happen that a hash is not listed in the online database either because the release is to new, human error or because it has been tampered with (say another language was added).

Still, Windows 7 ISO Verifier is a nice tool for users who download ISO images of Windows 7.

    Great tool but it's a little late don't you think? There's probably only going to be one more leaked build between now and Oct. 22.
  • Zach chance is that the developers continue the project once Microsoft releases updates (like the first service pack for Windows 7).

    Uh, why not just get it from the official source rather than unreliable and potentially harmful sources?

    I have been running Windows 7 RC for quite a while and it's absolutely awesome. It's really worth checking out and trying it out. It's my primary system now.

    For a couple of more days, Windows 7 can be pre-ordered at half the price (I think it's Microsoft's promotion). Since it won't ship until October, there is really no harm in pre-ordering it to get the price at 50% right now and you can always change your mind later. I already ordered a couple of copies.

    By the way, in case anyone is interested, I read about the promotion to get Windows 7 at 50% off initially at http://www.uberi.com

    Maybe someone will find it useful too.

    Because Microsoft has publicly only released two builds, the beta and the RC. Not everyone likes playing it safe; I for one used to download builds all the time between M1 (6519) and the beta (7000) but after the RC I haven't downloaded many since the OS is just so much more polished, and since after the RC no major features have been added.

    And of course, not everyone is able to download the TAP releases, which is why we're happy that those that ARE able to get them, upload them so the rest of us can see the improvements to the OS as it's development progressed.

    Last thing I'd like to mention is that an OS release is no different from any software released to the internet from "unofficial" sources - you need to use good judgement and take precautions to mitigate any potential damage caused if it's been tampered with. It's why I've not had a virus in 8 years (not since the Summer of Worms), and it's why I've chosen to buy a NAS box to do daily backups to. I wouldn't have bothered a few years ago.

    Thanks for the link by the way, some good deals on there :)
