Open Windows Contacts by clicking the Start button , clicking All Programs, and then clicking Windows Contacts.
Windows Contacts replaces the Windows Address Book found in earlier versions of Windows. Windows Contacts functions as the address book for Windows Mail. You can also use Windows Contacts by itself, to track information about people and organizations.
