So I updated my Lenovo 510p and my Asus VivoTab Smart. And I've noticed there isn't really customization. My lock screen picture can be changed and my desktop background and color can be changed. But they do not sync between the systems. Nor does the start menu sync between systems. And I've also noticed on my tablet when I swipe up my lock screen it has a different color and I can't change it. Just wondering if there is a way to change it or if its coming in future builds other than that not a problem with my systems so far!! Cortana is very buggy.
