First, viswagb, please re-register with a username following the JavaRanch UserName Guidelines. Your username has to be in the format "First Name" + space + "Last Name".
It sounds like you want to disable all keys when your login screen comes up, not allowing the user to use alt-tab to switch to another program, or Ctrl-C to kill it, or windows key to bring up menu. This isn't possible because Windows catches system keypresses like Ctrl-C, Alt-Tab, and windows key first and deals with them. There is no way a pure Java program can interrupt the OS from getting these key presses. (There may be able to be some way to use JNI to do this, but I don't know how to do it...)
