Users who own an official copy of Windows 7 from MSDN or TechNet may have faced problems where you wanted to install a separate version of Windows, only to discover that you will have to download a different ISO file just to install your desired version. Windows Vista had one ISO file installer for all the separate version of Windows. But Microsoft has changed this approach with it and started providing different ISO files for each version (Starter, Home Premium, Professional and Ultimate) of Windows. This results in an unnecessary strain on bandwidth when downloading and wastes space when archiving.

Now the good news for the users is that there are a few useful tools out there that can help you convert your prevailing ISO file to the required version. ISO Image Edition Switcher provides the comforts of Vista-like installing for users. All you require is a ISO disc image, and the ISO Disc Image Utilities will perform the rest for you. The two tools under focus are called ISO Image Edition Switcher and ei.cfg Removal Utility.

Unlike Windows Vista, it is no longer one disc to rule them all, which poses challenges to people who are downloading several versions from their MSDN or TechNet subscriptions, and for the users who want to backup and roll their ISOs, because instead of just two disc images–one each for 32-bit and 64-bit–now you have eight separate images.

ISO Image Edition Switcher changes formal ISO disc image of one version into formal ISO disc image of another version.
