A registry entry opened by a call to IVsFontAndColorStorage.OpenCategory closes automatically when:
CloseCategory is explicitly called.
The current instance of the IVsFontAndColorStorage interface is destroyed or
OpenCategory is called for a different Category.
Explicitly closing entries by calling CloseCategory is good practice as it ensures that no code reads from or writes to a Category that it is not supposed to.
