If you happens to download Windows 7 builds leaked around torrents or other sources on the internet, you might like to verify the integrity of files to ensure files are as described and have not been tampered with, however not everyone does this. Long Zheng with Sven Groot have created a little applet for Windows 7 ISO verifying pleasure. Just download the utility and drag and drop an .ISO file onto this EXE, or double click on it and navigate to the file, then sit back and relax whilst it crunches the numbers. Once it generates a hash, it’ll compare it with a list of known and trustworthy hashes of ISOs to tell you exactly which build version and architecture it is known to be. This list will be updated live over the web so you won’t have to redownload the app.
