Question

I want to kill a process programmatically in vista/windows 7 (I\'m not sure if there\'s significant problems in the implementation of the UAC between the two to make a diffe

You are correct in that it's because you don't have administrative priveleges. You can solve this by installing a service under the local system user and running a custom command against it as needed.

In your windows form app:

private enum SimpleServiceCustomCommands { KillProcess = 128 };

ServiceControllerPermission scp = new ServiceControllerPermission(ServiceControllerPermissionAccess.Control, Environment.MachineName, "SERVICE_NAME");
scp.Assert();
System.ServiceProcess.ServiceController serviceCon = new System.ServiceProcess.ServiceController("SERVICE_NAME", Environment.MachineName);
serviceCon.ExecuteCommand((int)SimpleServiceCustomCommands.KillProcess);

myProcess = System.Diagnostics.Process.Start(psi);

In your service:

private enum SimpleServiceCustomCommands { KillProcess = 128 };

protected override void OnCustomCommand(int command)
{
    switch (command)
    {
        case (int)SimpleServiceCustomCommands.KillProcess:
            if(killProcess)
            {
                System.Diagnostics.Process[] process = System.Diagnostics.Process.GetProcessesByName("MyProcessName");
                // Before starting the new process make sure no other MyProcessName is running.
                foreach (System.Diagnostics.Process p in process)
                {
                    p.Kill();
                }
            }
            break;
        default:
            break;
    }
}
