The big news with this update is that it allows you to turn on Smart App Control without needing to install a fresh copy of Windows. That's assuming of course that you want to turn it on. A very basic way of describing Smart App Control is to think of it as fully automatic white listing, where only approved apps & files are permitted to run.

Smart App Control ensures only signed code runs or code predicted to be safe by our intelligent cloud-powered security service.
