This week, Microsoft officially launched Windows Phone 7 – its latest mobile operating system.

As we prepare for handsets based on the mobile OS to be made available, here's a look at the hubs dedicated to activities such as pictures, office, people, Xbox gaming, music and video.

Start screen

The new home screen, or Start, as Microsoft calls it, contains a series of 'live titles' or widgets, which can show you at a glance your missed calls, incoming texts or email. You can also add 'live titles' from friends' social network profiles, such as from Facebook.

Pictures Hub

The Pictures Hub collects photos you've taken with your Windows Phone 7 camera, photos synced from your computer, and your albums from social networking sites. The Pictures Hub also aggregates any videos you might have.
