Correct, it makes a copy, so your code is safe.

The EventType object that gets passed through the handlers is actually
the one you provide yourself in your event loop, where you call
EvtGetEvent. That API copies the event data into your EventType
structure, and does not return a pointer to anything internal or to
anything that must be freed. So you can do whatever you want to that
structure after calling EvtGetEvent.
