"To inaugurate" is fairly archaic in American English. We say people get inaugurated in political office, or to inaugurate a new policy. I couldn't tell you exactly what the difference is, but I can't remember the last time I heard someone use the word for anything but a new president.
To say something "launched" implies movement, and a certain element of risk. Its usage is metaphoric, as literally speaking only vessels launch. When you "launch" a new software, you are taking it from its safe harbor (the development team) and putting it out into the dangerous seas (the general public). It used to imply adventure and risk, but is now sufficiently commonplace that people don't normally think of it that way. "Released" is a more neutral word for the same thing.
The difference is in the degree of change applied to the object.
Enhancing leaves the main structure and functionality the same, most features intact, and generally speaking improves the object by applying small modifications.
Revamping often changes the basis, some fundamentals, some key features. Structure can undergo some changes, but the functionality generally is kept as is although we can see re-prioritizing of some elements.
Overhauling involves disassembling into constituent parts, examining each of them carefully for flaws, replacing with equivalent new parts (subsystems), in order to bring the system's performance closer to the original specification/idea.
Those words are not interchangeable. You could overhaul an engine of an aircraft to bring the engine back to its "factory new" performance. You could enhance an engine of an aircraft by replacing some heavier parts with lighter ones, for instance. You wouldn't revamp an engine. The latter most often used to describe a process for making fixes in a social/business system, like government, company management, etc. You could, however, revamp a design of an engine, which often includes technological part (manufacturing).

The common thing between the two is they describe a nonphysical part of a person. Now lets define each to get the difference.
Usually when you say "spirit" you are referring to the attitude of a person. It describes emotional things like motivation, courage, enthusiasm, etc.
"Mind" on the other hand describes the intellect and intelligence. The part of a person that has sense and logic and is not driven by emotions. The part that processes and memorizes things.
