I was just playing with it and Windows and Doors are not effected , only the Wall is "Shaped".   If you meant Windows and Doors themselves you can't shape them with this trick AFAIK , you need to use the SHAPE or ARCH Tab in the DBX to change them but the ARCH Tool is limited and buggy.... see pics   One quirk with Half Wall I found was I need to click the Break Line Tool after selecting the Wall to get the Edit Handles...on Full Height walls this is not needed.
