With Excel automation, the app is hidden upon creation and can be made visible using the Visible property. Maybe this behaviour applies also to PowerPoint. Is PowerPoint really visible after calling CreateDispatch?

Can't be sure it's what you want, since I don't know your intention.

However, by default it's not visible when started using automation features.
The following works for me from excel VBA. No PPT window is shown, the file is created, the application doesn't remain in the task manager.

VB

Sub CreatePptFileInBkg()
    Dim ppt As Object
    Dim curPres As Object
    Set ppt = CreateObject("PowerPoint.Application")
    Set curPres = ppt.Presentations.Add
    curPres.SaveAs FileName:="c:\PPTSample1.pptx"
    ppt.Quit
End Sub
