How to create an endless process?

Simple question, how do I make my application process "unstoppable" by the system? I want when a user tries to close the application the message "Access is denied" appears, and when it forces the kernel to terminate the CRITICAL_PROCESS_DIED kernel error. This is what happens with the wininit.exe process by the CMD:

C:\> taskkill /im wininit.exe
ERRO: o processo "wininit.exe" com PID 532 não pôde ser finalizado.
Razão: Acesso negado.

Not even the WinInit process is displayed in the task manager. Can you programmatically make the application close without any problems and another time be endless?

I found this class in another OS question:

Public Class CriticalProcessInformationProcessor
    <DllImport("ntdll.dll", SetLastError:=True)>
    Private Shared Function NtSetInformationProcess(hProcess As IntPtr, processInformationClass As Integer, ByRef processInformation As Integer, processInformationLength As Integer) As Integer
    End Function
    Public Shared Sub EnableCriticalProcess()
        Dim isCritical As Integer = 1
        ' we want this to be a Critical Process
        Dim BreakOnTermination As Integer = &H1D
        ' value for BreakOnTermination (flag)
        Process.EnterDebugMode()
        'acquire Debug Privileges
        ' setting the BreakOnTermination = 1 for the current process
        NtSetInformationProcess(Process.GetCurrentProcess().Handle, BreakOnTermination, isCritical, 4)
    End Sub
    Public Shared Sub DisableCriticalProcess()
        Dim isCritical As Integer = 0
        ' we want this to be a Critical Process
        Dim BreakOnTermination As Integer = &H1D
        ' value for BreakOnTermination (flag)
        Process.EnterDebugMode()
        'acquire Debug Privileges
        ' setting the BreakOnTermination = 1 for the current process
        NtSetInformationProcess(Process.GetCurrentProcess().Handle, BreakOnTermination, isCritical, 4)
    End Sub
End Class
