When I type ipconfig in (Run) my Dos Window appears then drops
That is because you are running a DOS-mode program that opens a
console window to display its stdout (standard output). When the
program exits, the console window also closes. If you want the
console window to remain open, have something else keep it open: run
"cmd.exe" which is the command-line interpreter that also opens its
own console window. Then when you run other DOS-mode programs within
that shell, the console window remains open (because you exit the
program but not cmd.exe to which the console window belongs).
So, run "cmd.exe" and then run your DOS-mode program. There should
already been shortcuts in your Start menu to run a "Command prompt"
(aka DOS shell) which run the cmd.exe program.
