How do you Switch User?

Question

We're upgrading some work PC's to Windows 8, so for those users that fear change I've written a small helper app to help them log off (to keep them away from Metro, where possible).

The app works just fine except that I cannot find out how to Switch User. I've looked at all the switches for the shutdown command (shutdown -?) but I cannot find any reference to it there.

Can anybody please shed some light on how I achieve this? Thanks.

Private Sub Event_Click(ByVal Sender As Object, ByVal e As EventArgs)

    Dim ActionButton As String = Sender.Name

    Select Case ActionButton

        Case "ShutdownButton" : Process.Start("ShutDown", "/s /t 0") : Exit Select
        Case "RestartButton" : Process.Start("ShutDown", "/r") : Exit Select
        Case "LockButton" : LockWorkStation() : Exit Select
        'Case "SwitchUserButton" : ??? : Exit Select
        Case "LogOutButton" : System.Diagnostics.Process.Start("ShutDown", "/l") : Exit Select
        Case "HibernateButton" : System.Diagnostics.Process.Start("ShutDown", "/h") : Exit Select

    End Select

    Me.Close()

End Sub

I believe the most fastest way is to Win>L and press "Switch User", though you can't do the second step programatically... there's no real command to switch user.
