Norton utilities 16

What exactly is the utilities 16 program supposed to do?It says you need to clean your registry it sets up the restore points then it says you need to defrag your disk AFTER the registry scan,and when you start to defrag  it pops up and says you will lose your restore points (that were set up during  the registry clean) Then when you start to defrag it pops up the ignore,cancel retry screen and says you will lose your restore points if you continue with the defrag. Sounds backward to me?whats up?Why does the program have you do it in that order? Seems to defeat the purpose.What am I missing?.
