In RSView 32 in the project tree there is a startup tab try some of the settings there but I advise you read the help files first as it can make the times you tourself wish to access windows not an easy task.
If your operating system is win 2000 or XP you can use desktop lock which is found from <Startup> <Program Files> <Rockwell Software> <RSView 32 Tools> <Win 2000 XP Desktop lock>
Again read the <Win 2000 XP Desktop lock help> file.
