The Welcome screen is displayed by default on Windows XP Home Edition-based computers and on Windows XP Professional-based computers that are not members of a domain. Under your name on the Welcome screen, there is a hyperlink that indicates the number of unread e-mail messages. If you click this link, it reveals which account the messages are from, and how many each e-mail provider contains. For example, if you have three unread e-mail messages, and you click the hyperlink under your name, you see the following information (where UserID is your user name for the corresponding e-mail account):
UserID@msn.com (2) UserID@hotmail.com (1)
The hyperlink is displayed only if you have an e-mail client that is capable of updating the Welcome screen running on your computer. Currently, Microsoft Outlook Express and Microsoft Windows Messenger support this feature.

To block only one of the e-mail clients from updating the Welcome screen, permissions to the registry key under UnreadMail" that specify the e-mail account must have System permissions set to read-only. For example,assume that you have the two following registry keys under the UnreadMail key:
