In order to receive Windows Messages, your program must have a window. As noted on the SessionSwitch MSDN page:
In a Windows service, unless a hidden form is used or the message pump has been started manually, this event will not be raised.
A link is included which gives an example showing how to receive these events with a hidden window. Message Only Windows are another, similar option for receiving window events and messages.
