• relaxed sandbox for trusted applications
– no network restrictions on ports and x-domain/x-scheme access

– access to the keyboard in full screen mode
– window options – alter chrome and offer alternate move/resize options

• trusted applications can call to COM code
– IDispatch interface only
– must be registered with a ProgId IDispatch
• programmability is via late binding must have a
– dynamic in C#
