Recent versions (unsure when this changed, but fairly recent), maintain a handle to the drive (Directory?) used to copy the disk to (using dvd copy) even when the copy has finished. (i.e. prompt popped up).
In older version, this handle was released apparently released (or at least handled differently so that the computer wasn't prevented from going to sleep).
This matters, because windows will not automatically go to sleep if there is a handle to a network drive. So if one is copying the disk to a network drive (say a large windows share where one stores their backups), right before one goes to bed, the computer will remain awake the entire night (though at least, the user gets to sleep , wasting a decent amount of power.
