Why are you doing System type stuff using Java? It is not designed for it. If you want a command line command to get the "application" list that appears in TaskManager, then why are you asking in a Java forum? Ask in some Windows forum somewhere.

Edit: And this is the JSP forum. What you have posted is not JSP, but rather Java (nominally).

Add the /v flag (verbose) on tasklist to see the application names "tasklist.exe /nh /v"

Because, his question was not about how to use Runtime.exec. He, suppossedly, knew how to do that already. His question was about which command to use, and that has absolutely nothing to do with Java, and so did not belong on this forum. So the advice given (to ask on a Windows forum or do some searching on his own) was spot on. Whether you like that fact or not does not concern me.

It also had, still does not have, absolutely anything to do with JSP, even if he was asking about how to use Runtime.exec. So keep your opinions to yourself, or at least make your remarks relevant. Anything else is a simple, whining, rant.
