How does Windows perform synchronized GUI animations?

When I use Spy ++, I noticed that the mouse entering the button launches the WM_TIMER series.

How does windows do this? Does he ask to notify about it or to call the function pointer after X milliseconds or does the widget register its own proc timer?

The reason I want to know this is because I am creating a gui api game in C ++ and want to enable this mechanism.

Animation options in the MS Windows GUI are very limited. You can't say anything if you knew a real OS with animation support, such as Mac OS X.
