I can see the purpose of a Lock Screen if you actually lock your screen after boot up. Like when you step away from your computer to get some coffee, you can press <Windows Key + L> to keep prying eyes and hands away from your work. (With Windows 8 Metro, there's probably a more convoluted path to do it, I'm sure. :lol
However, why the extra step during the boot process? Why not boot directly to the log-in screen? (Or, presumably, if you have a single user with no password, directly to the Start screen?)
Is there a way to do that: boot directly to the log-in screen, bypassing the Lock Screen?
