I think what we are saying is that maintaining file integrity isn't much of an issue that any of us have seen with Win7, so the actual problem might be the way the file checking program interacts with Win7 causing it's output to be possibly faulty.
Sometimes I copy multiple ISO's, extract, recompile dozens of times and have never had any file degradation with Win7. The only need to check file HASH was when the download source was questionable, but never after it got onto Win7.
What I would do next in your situation is go to the website for the file checking program and find out the best way to approach them - forum, email, chat, phone - then ask for a definitive answer to your problem.
