I just did a quick search, found a utility here (scroll down to ConsoleTool)
/HIDE hides the console window of course.
/SHOW shows the previously hidden console window.
/NOMENU removes the system menu from the console window.
After using one of these parameters your batch files keep running. Make sure to test them properly before using the /HIDE switch.
Use this commandline utility from within batch or CMD files if you want users not to interfer with or close certain console windows.
Quite handy for securing Windows NT and Terminal Server login-scripts.
ConsoleTool is Freeware and provided as is. Use at your own risk !!
You may freely redistribute ConsoleTool free of charge.
