Unlike Microsoft SMS Support WebCasts which are one-way (the information is broadcast to you), Technical Chats allow you to 'talk' to Microsoft in real-time using the Microsoft Chat Software (which you'll need to download to take part in any of the chats).

You can see the current list of Technical Chats at:
