With the help of Sven Groot, we came up with this little applet for your Windows 7 ISO verifying pleasure.
It couldn’t be any easier to use. Simple 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.
