Answer 1

By not providing DeviceUniqueId in Windows Phone 8 and Windows 8, Microsoft tried to avoid User Tracking but with increased pressure from Dev community, they are bringing it back again.

In Windows 8.1, Microsoft has introduced a new AdvertisingId API and may also bring similar Id to identify a unique user across apps in subsequent Windows Phone 8.1/9 versions.
