In Windows 8 and Windows RT, there are a few new places to show your favorite pictures and colors. On the Start screen, you can change the background and color. The background shows up only on Start, but the color you pick shows up in a few other places too, like the charms and the sign-in screen. You can also make sure there's a favorite photo waiting to greet you on your lock screen, and choose a few apps to show you info and updates you might have missed while your PC was locked. And you can add some excitement to your account picture — if you have a webcam, you can create a video clip to use instead of a photo. Or if you have photo editing apps, you can use them to add some finishing touches to a photo.
