Having used RT Se7en Lite in the past, I found WinKit, but I seem to have hit a brick wall before I have started; WinKit asks for a WIM file even on the Basic tab - what is a WIM file? Anyway, I'll explain what I want to do, and perhaps someone can help. I've got a Dell Mini 9 with a 16GB HD, so I'm trying to get my image reasonably small: a customised "Lite" version. My starting point is an ISO of Windows 7 Home Premium 32-bit, and a Microsoft Update Standalone Package (.msu) file of Windows 7 32-bit SP1. My desired end point is a Windows 7 Starter ISO, with SP1 integrated and several unwanted components(such as Language Packs, modem support, other display drivers etc) removed. It would be nice if I could customise the Windows 7 Starter wallpaper (as this is not normally possible) but I can live without this. Can someone please tell me the steps I need to follow?
