How to make Kiosk mode Window form?

well i found a way to disable the ctrl+alt+del and its through using any event like if the user move his mouse then ill just call the

public bool FindAndKillProcess(string name)
{
//here we're going to get a list of all running processes on
//the computer
foreach (Process clsProcess in Process.GetProcesses()) {
//now we're going to see if any of the running processes
//match the currently running processes by using the StartsWith Method,
//this prevents us from incluing the .EXE for the process we're looking for.
//. Be sure to not
//add the .exe to the name you provide, i.e: NOTEPAD,
//not NOTEPAD.EXE or false is always returned even if
//notepad is running
if (clsProcess.ProcessName.StartsWith(name))
{
//since we found the proccess we now need to use the
//Kill Method to kill the process. Remember, if you have
//the process running more than once, say IE open 4
//times the loop thr way it is now will close all 4,
//if you want it to just close the first one it finds
//then add a return; after the Kill
clsProcess.Kill();
//process killed, return true
return true;
}
}
//process not found, return false
return false;
}

i just want it to be like kiosk mode... i would really appreciate it if you can help me and beside your the one helping me ever since i start posting here in codeproject ^_^ thanks a lot and if you have other way to disable the ctrl+alt+del without using the gina.dll then i would really be happy to know another way

well what im doing is just when the user move his mouse or do any action that will trigger my global hook i just simple check if there is an existing process running namely taskmgr.exe if i was able to find such process then i just kill it using
clsProcess.Kill();

so basically im when the user trigger the globalhooks i just simply check the task manager if the taskmgr.exe is running if its true i just end its proces..
