App sem janela

E ai galera,

Preciso que meu app nao abra nenhuma janela, e fique apenasem 'processos' do gerenciador de tarefas

Sera que tem como fazer isso?

App:

Public Class PegaTela
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
PrintaTela()
End Sub

Public Shared Function GetWindowCapture() As Image
SendKeys.SendWait("^{PRTSC}")
Dim objClipboard As IDataObject = Clipboard.GetDataObject()
Return objClipboard.GetData(DataFormats.Bitmap)
End Function

Public Shared Sub PrintaTela()
Dim aData As Array = Split(Date.Now, " ")
Dim aNome As Array = Split(aData(0), "/")
Dim vNome As String = ("c:\System_PRTSC-" & aNome(0).ToString & aNome(1).ToString & aNome(2).ToString & "-" & Replace(aData(1).ToString, ":", "") & ".bmp").ToString
GetWindowCapture().Save(vNome.ToString)
System.Threading.Thread.Sleep(900000)
PrintaTela()
End Sub
End Class
