I’ll post a link to my favorite one here. Then you calculate, generate, or produce in some manner the MD5 of the file you have on your computer using any MD5 calculator. Yes, you get them ( the MD5, and also the ISO) from a source, whether that source is directly from µSoft or someone else. later I read somewhere else what the MD5 checksum was supposed to be for the ISO. I doubt that many people received a bad download from µSoft but it is possible. Microsoft’s download manager applet for the RC had an MD5 checksum built into it, according to a source… it didn’t either display it or notify you if it was valid, it simply would fail a bad download from microsoft if it didnt match. It is recommended you take personal care when using any ISOs. Update 3: With the wider public release of Windows 7, this tool is no longer kept up to date with the many and numerous versions of Windows 7 SKUs and languages. Update 2: Added support for official retail US English RTM ISOs. Update: As a few users have noted, this only works for English versions of Windows 7 ISOs so far. The information is provided only as a guide and cannot be used as evidence in an internet argument. This list will be updated live over the web so you won’t have to redownload the app.ĭownload the Windows 7 ISO Verifier (EXE, 253KB)ĭisclaimer: Like most entrepreneurs, I take no responsibility for the consequence of using this application. 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. 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. With the help of Sven Groot, we came up with this little applet for your Windows 7 ISO verifying pleasure.

Leading up to the inevitable leak of the Windows 7 RTM build like a bottle of champagne shaken once too many times, I wanted to make this process of verifying file hashes even simpler by making it easy and convenient to generate and compare the hashes.

Of course I would know very little about how this works, but I understand that there is a process of verifying the integrity of files to ensure files are as described and have not been tampered with, however not everyone does this. Just between you and me, I’ve heard that one could obtain copies of Windows 7, including builds newer than the public betas, from some not-so-sanctioned sources.
