How to Export a Mac Address Book to Windows

Address Book on the Mac has an export feature that can make a copy of your contacts as a .vcf file. You can transfer .vcf files—the most common format for contacts—from platform to platform. After you export the contacts, get the file to your Windows computer in some fashion; from there, import the file into your existing Windows Contacts. The .vcf file will be relatively small (provided you don't have an excessive number of contacts), and you can even email it for use on Windows computers.
