Lock operators out of Windows

[GRMAN]

Hello all, is there any way that i can lock operators into My Labview application and not let them use any other programs on computer. Any help is greatly appreciated.
Thanks.

You must use Windows 2K or XP. Put your Labview app in unique directory. Create a unique user name and password using User Manager. Use permissions to restrict the new user name to allow read/write/execute to the Labview app directory, and do not allow anything to other directories. You will have to change permissions on every other directory so as to remove "everyone" from accessing. When the user logs in, he will not be able to access anything except whatever is in the LV directory.

There is a program called keyblock that I have used. It is available for download at: http://www.phord.com/keyblock.html. This will prevent users from using ctrl-alt-del or the windows button. You can use the trial version for free, but it is not password protected. That has worked good enough for us because the operators don't know how to unload the program.
