Как я могу запустить свое приложение перед входом в систему VB.NET

---

Hi guys so my question is how would i make my vb net program start before login and i know someones going to say well make a windows service but I've tried and my code doesn't work for some reason. So does anyone know how i make the code that ill put below into a file system watcher its for a md5 monitoring program so i can stop certain files from entering my computer a little of a do it myself thing heres some of the code the only part that im having problems with no errors just dont work in a windows service application.

Private Sub FileSystemWatcher1_Changed(sender As Object, e As FileSystemEventArgs) Handles FileSystemWatcher1.Changed
      Dim abc As New Service1()
    Try
        abc.Labellastreal.Text = e.FullPath
        ListBox3.Items.Add(abc.Labellastreal.Text)
        abc.OpenFileDialog3.FileName = ""
        Dim scanbox As New TextBox
        scanbox.Text = My.Computer.FileSystem.ReadAllText(Application.StartupPath & "\Database\VirusList.dat").ToString
        Dim md5 As New MD5CryptoServiceProvider
        Dim f As New FileStream(e.FullPath, FileMode.Open, FileAccess.Read, FileShare.Read, &H2000)
        md5.ComputeHash(f)
        Dim hash As Byte() = md5.Hash
        Dim buff As New StringBuilder
        Dim hashByte As Byte
        For Each hashByte In hash
            buff.Append(String.Format("{0:X2}", hashByte))
        Next
        f.Close()
        If scanbox.Text.Contains(buff.ToString) Then
            Me.OpenFileDialog3.FileName = e.FullPath
            file.delete(Labellastreal.Text)


        End If

    Catch exception1 As Exception
        ProjectData.SetProjectError(exception1)
        Dim ex As Exception = exception1
        ProjectData.ClearProjectError()
    End Try
   End Sub 

and obviously theres a filesystem watcher event for created and renamed.

Что я уже пробовал:

я пробовал все несколько разных вещей, но в настоящее время хочу/ задаюсь вопросом, Может ли кто-нибудь помочь с услугами. Овации.
