How to hide the running of programs _ Web surfing

The easiest way to hide a program's operation is to set the form's visible to false. But just using Ctrl+alt+del to exhale the list of programs is completely out of the box. So how do you completely hide the running program? It's actually very simple.
We know that there are a lot of programs running in the background. But only a few of them appear in the list of programs, and most system programs do not appear. In fact, a process that is registered as a "server" does not appear in the list of programs.
API functions used: Hot Network
Private Declare Function getcurrentprocessid Lib "kernel32" Alias "GetCurrentProcessId" () as Long
This function can get a unique identifier for the current process.
Private Declare Function registerserviceprocess Lib "kernel32" (ByVal dwprocessid as Long, ByVal dwtype as long) as long
This function registers or dwprocessid a process ID number as a "server".
Constants used:
The constant here is the value of the dwtype.
Const Rsp_simple_service = 1
Register as "server".
Const Rsp_unregister_service = 0
Cancel the "server" registration.
Program:
Public Sub Makemeservice ()
Dim pid as Long, reserv as Long
' Get current Process ID
PID = GetCurrentProcessId ()
' Register as a server
Regserv = registerserviceprocess (PID, Rsp_simple_service)
End Sub
Public Sub Unmakemeservice ()
Dim pid as Long, reserv as Long
' Get current Process ID
PID = GetCurrentProcessId ()
' Cancel Server Registration Hot Network
Regserv = registerserviceprocess (PID, Rsp_unregister_service)
End Sub
However, this method does not guarantee that the program will not be detected when running, such as using the program hunter can be traced.
