If like myself, you have customers using different versions of Windows 7, do you need to bring along all Windows 7 DVDs of all the different versions?
Fortuntely I found out just recently, you don’t have to! DUH! 😛
It will be easier to do this if you install using USB drives. All you need to do is look for the file ei.cfg which is located in the folder Sources and just delete it and hey presto! you now can install different versions of the Windows starting with Windows 7 Starter to Ultimate!
