The user has more control over UWP apps accessing the file system. Selected UWP apps will be granted permission to have broad file system access. If an app has the file system access restricted, a consent message will pop up, asking the user if they want to confirm or deny the request.

Added a new power management scheme called "Ultimate Performance". This is only available in the Pro for Workstations SKU.
Made the tiles for some UWP app placeholders when connecting to the internet on the Pro for Workstations SKU productivity and enterprise focused instead of being consumer focused.
