How to make a command window invisible t

When any program is run from the command prompt, the command window is visible to the users. I want to run a program which only runs from the command prompt. I have placed it in the startup folder os all users under windows NT. The program runs but it is visible to the user. The user can close it at any time. I want the program to run in the background but it should be invisble to the users i.e. it should not appear on the task bar or on the desktop. Any bright ideas to help me out?
