Stop and disable service

Question

Hello,
I used this 2 lines to stop and disable startup of a service:

System.Diagnostics.Process.Start("SC", "Stop blah")
System.Diagnostics.Process.Start("SC", "Config blah Start=Disabled")

Using .net framework 4.7 I wanna do it this way (don't wanna use process/SC anymore):

Dim svc1 As New ServiceController("blah")
svc1.Stop()
svc1.StartType = ServiceStartMode.Disabled

but StartType is read-only! any idea?

ChangeServiceConfig works for me (as Admin, with a Manifest)

Test with a random service :

    Dim scServices() As ServiceController  
    scServices = ServiceController.GetServices()  
    Dim scTemp As ServiceController  
    For Each scTemp In scServices  
        If scTemp.ServiceName = "XamlSpySvc" Then  
            Dim bRet As Boolean = ChangeServiceConfig(scTemp.ServiceHandle, CUInt(SERVICE_NO_CHANGE), SERVICE_DISABLED,  
                           SERVICE_NO_CHANGE, Nothing, Nothing, IntPtr.Zero, Nothing, Nothing, Nothing, Nothing)  
        End If  
    Next scTemp  

with declarations :

<DllImport("Advapi32.dll", SetLastError:=True, CharSet:=CharSet.Unicode)>  
Public Shared Function ChangeServiceConfig(<[In]()> ByVal hService As SafeHandle, ByVal dwServiceType As UInteger, ByVal dwStartType As UInteger, ByVal dwErrorControl As UInteger,  
                                              <[In](), MarshalAs(UnmanagedType.LPWStr)> ByVal lpBinaryPathName As String, <[In](), MarshalAs(UnmanagedType.LPWStr)> ByVal lpLoadOrderGroup As String,  
                                              ByVal lpdwTagId As IntPtr, <[In](), MarshalAs(UnmanagedType.LPWStr)> ByVal lpDependencies As String, <[In](), MarshalAs(UnmanagedType.LPWStr)> ByVal lpServiceStartName As String,  
                                              <[In](), MarshalAs(UnmanagedType.LPWStr)> ByVal lpPassword As String, <[In](), MarshalAs(UnmanagedType.LPWStr)> ByVal lpDisplayName As String) As <MarshalAs(UnmanagedType.Bool)> Boolean  
End Function  

Public Const SERVICE_NO_CHANGE As UInteger = &HFFFFFFFFUI  

Public Const SERVICE_BOOT_START = &H0  
Public Const SERVICE_SYSTEM_START = &H1  
Public Const SERVICE_AUTO_START = &H2  
Public Const SERVICE_DEMAND_START = &H3  
Public Const SERVICE_DISABLED = &H4  

Answer 2

Another option may be to set the DWord service subkey registry Start value to 4
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DialogBlockingService

Answer 3

ServiceController.ExecuteCommand maybe?!
