Timers set using the SetTimer API require a Windows message processing function to be actively running, as that is where the time messages are sent.

If you need a timer thread then you could register a Window class and create a default window message pump (See this article for a short example), but a simpler process would probably be to just spin up a second thread to handle your timing events and send notifications.
