[Harry Potter] Does the Time Turner demonstrate there is no free will in the Potterverse?

When Harry and Hermione used it, nothing changed.  They, in fact, participated in events exactly as they remembered them from before the Turner was used.  That would seem to indicate that they had no choice but to act as they did, even though they didn't seem to know their actions were constrained in that way.   

So is this an indication that there is no such thing as free will?

Not at all. It's simply a stable time loop. Think about the documentary of the WyldStallyns before they revolutionized the world: *"Remember the garbage can,"* <trash can falls on the head of person in front of Bill>. The events only transpire the way they do because they resolved to make those decisions. Every result was directly from their personal choices, not predestination.
