This has happened to our ES more than once. All the windows, with the addition of the sunroof slide open by themselves while the car is locked... even though the unlock button was not pressed to allow this function to take place.. Whats the issue here?

 

The problem is most likely that something in your pocket or wherever your key fob is has pressed against the unlock button. I did however have a car doing something similar even while the car was being driven that turned out to be a defective switch assembly for which there was a TSIB - so have it checked out.
