> 
> People were confused on a few details around fixing windows space names, including:
> 1. setshortname can report confusing error message when the directory is in use
> 2. Many directories can have names set but only Microsoft Visual Studio and Windows Kits need them
> 
> Also adds some notes about `jdk` being the exploded image while `images/jdk` is the actual image.
