¿Alguien tiene alguna idea?

To efficiently keep track of the windowing data for all windows without polling you have to register for notification of window creation or deletion and then hook all their message queues and process messages that affect the windowing data you are trying to track. Unfortunately, this is quite a substantial task. If you want a head start, you can take a look at how Spy++ is implemented and so something similar. Here's an article:
After looking at that you might was to re-consider just polling every so often and carefully update only the changed data in the
