I want to know the answer to the following question:
What features were added to the lock screen?
All the background I'm provided with is that "Windows 8 also adds native support for USB 3.0 devices, which allow for faster data transfers and improved power management with compatible devices, and hard disk 4KB Advanced Format support, as well as support for near field communication to facilitate sharing and communication between devices.". Is that enough to answer the question?
Answer: no
