Windows includes a contact manager application, called the Address Book, that you can use to store information about your friends, family, and business associates. You can then import this contact information into Outlook Express (to send email), Microsoft Works Calendar (to remind you of birthdays), and Microsoft Word (to personalize letters and address envelopes and labels).
To add a new contact to your Address Book, click the New button on the Address Book toolbar, then select New Contact. Enter all the information you know (you don't have to fill in all the blanks), then click OK.
