If you’re reading this then you’re probably a geek. And you probably downloaded Windows 7 from TechNet or MSDN last week. You’ll have noticed that MS did not take advantage of WIM files (multiple images in one file thanks to single instance storage of the contained files). Normally you boot up the DVD/ISO and choose and edition to install. However, the ISO’s that MS shared last week are specific and at first glance, only contain 1 edition, e.g. Business, Ultimate, etc.
Wes Lazara posted this and something else over the weekend. On inspection, the INSTALL.WIM file does contain the other images – as we would have expected originally. It’s just MS placed a file called EI.CFG on the DVD to restrict what the installer would show. Why? I’ve no idea. It seems dumb to me. One of the great things about WIM is the ability to have more than one image. Does Microsoft think we’re dumb and need help in this matter? If you are that dumb should you really be installing an operating system?
