Retardation

Okay, im doing a project in school in which our teacher wants us to be able to simply installing Windows Vista by just using an usb 2.0 without clicking any next questions during installing to able to install vista on many computers easily without taking to long time and being effective. I guess i should use vlite and as i understand it it's a program that "Changes" the iso file with windows vista somehow. Is there a tutorial or something somewhere? Or can someone help me quickly?
