While the power users probably have all of these in hand, Microsoft's latest batch of YouTube videos show off the new features in Windows Phone 8, such as the Kids Corner, lockscreen customisations, the app switcher, NFC sharing, and more...

We have:

• Running late in WP8.
• Create a new room in WP8.
• Set up Kids Corner.
• Bing your lock screen.
• Switch between apps.
• Text a reply to a phone call.
• Tap phones to share a photo over NFC.

And you'll find them all on Microsoft's YouTube channel.
