Windows Live Mail
Windows Live Mail is the latest incarnation of what used be called Windows Mail (in Windows Vista) and Outlook Express (in Windows XP and previously). Live Mail, shown in Figure 3, is a basic email program you can use to send and receive traditional POP email.

Beyond traditional POP email, you can also configure Live Mail to send and receive email from various web-based email services, including Hotmail and Gmail. It also offers a robust spam filter, as well as a phishing filter to protect against identity theft.
That said, Live Mail is more than just an email program. It also functions as a USENET and RSS newsreader, and offers calendar and contact management functionality. As such, for many users it is an adequate replacement for the more fully featured (and much more expensive) Microsoft Outlook program.
By the way, don't confuse Windows Live Mail with Windows Live Hotmail, which is a web-based email service. Windows Live Mail is a traditional email client software, not a web-based service.
