I talked to my client and had him install Windows Live Mail.  It copied all his folders, account and address book from Windows Mail automatically.  He is going to do the Win 7 upgrade tomorrow and from what I can find around the web that should work OK, since it's an in place "upgrade"  Worst case he will have to reinstall Windows Live Mail again and since it's already on the PC hopefully there will be no problems. With other versions of Windows this wasn't an issue since the OS came with an e-mail program. Thanks/Jack
I have a client that is going to upgrade his Vista 64 to Win 7 64 bit.  He is now using Windows Mail.  As Win 7 does not come with an e-mail program will the "upgrade" bring over the Windows Mail? or will he have to download an e-mail program (Windows Live Mail?).  If he downloads Windows Live Mail, will it import his existing Windows Mail address book? I'm using Outlook 2003 so I shouldn't have any issue when I install Win 7 so I can't recreate the problem.   
Win 7 Upgrade and Windows Mail?
