It seems that you were looking for environmental variables that are available in the command prompt. You can get a good listing of these variables and what they are on your system by opening a cmd window and typing the command set.
As far as the forum is concerned, it is true we all donate time and expertise with no expectation of reward. And while we cannot be charged with wrongdoing if someone were to use our advice for nefarious purposes, we also do not like to think that we are willingly helping anybody who may have nefarious purposes in mind. This is why you may have felt you were being scrutinized so intently, because in all honesty, making something completely "Stealth" is not usually a requirement unless there is something the programmer doesn't want the end user to be aware of. It has a very bad feeling to it to those of us who have worked the programming side for any period of time.
My suggestion for future requests, should you have any, would be that honesty is truly the best policy. Be blunt and always try to give as much information as you can. This forum is not to provide corporate solutions, but if someone is up front about them trying to figure out s particular solution for their job, they may get a PM from someone with a few suggestions. We don't need to know exact pathnames if it is irrelevant to the program, or how your network is constructed of it is irrelevant. But if we feel you are hiding something, alarm bells start going off and we get very wary of what is being asked.
Apologies if you felt offended, and please realize that it wasn't personal at all.
