Interesting little find I came across........... :cc_surrender:

This is a little tool for people who download images from MSDN or TechNet. Let's say that you've downloaded the 64-bit Ultimate ISO from MSDN. For some reason, you also want the 64-bit Professional ISO. You can either sit through another download from MSDN (takes time and wastes bandwidth), or you could make a copy of your Ultimate ISO and convert that into a Professional ISO, because, except for a handful of bytes, the two are virtually identical.

This is a set of binary patches (and a tool to apply these patches) that does this conversion between RTM disc images. The converted ISO will be exactly the same as what you download from MSDN/TechNet, and the SHA-1 hashes should match those officially posted by Microsoft. And obviously, you will need to already have one of the official disc images in order to use this. It's just something to prevent unnecessary downloads and let you back up these ISO images with far less duplication of data.

There is also a second, alternate utility available that "deletes" ei.cfg from the ISO image, thus converting any Windows 7 disc into a "universal" disc. It works by directly modifying the ISO's file table, so there is no need for a time-consuming extraction and rebuild (it will be done in less than a second), and the process is completely reversible. Both utilities can be found at the download link below.
