Introducing Windows Messenger

Most users will use Windows Messenger, shown in Figure 10.1, as an instant messaging program. It's totally compatible with MSN Messenger, so you can talk online with anyone who's using either one of the two programs. (As is common with instant messaging services, you can't use Windows Messenger to talk to anyone using AIM, ICQ, or Yahoo! Messenger. None of these programs talk to one another.)

• Make a phone call to anyone with a telephone (for an extra charge)

• Invite another Messenger user to play an online game

• Receive notices regarding the status of your stocks and securities

What You Need to Use Windows Messenger

To use the basic instant messaging features, you don't need anything more than you already have a computer, an Internet connection, and a copy of Windows XP. To use the telephony features, you need a full-duplex sound card and speakers, as well as a microphone of some sort connected to your computer. (You can substitute a headset for the speakers and microphone.) To make video calls or hold video conferences, add a PC camera to the mix.

In addition, if you want to use Windows Messenger, you need to sign up for a Microsoft Passport. Of course, if you subscribe to any other Microsoft service, such as Hotmail, you already have a Passport. It's Microsoft's way of keeping track of you, wherever you go. (Or, to be positive about it, it makes it easy to use multiple services with a single ID and password.)
