The information in this article applies to:

Microsoft Windows XP Professional

IMPORTANT : This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the “Restoring the Registry” Help topic in Regedit.exe or the “Restoring a Registry Key” Help topic in Regedt32.exe.

SUMMARY
The Welcome Screen is displayed by default on Windows XP Home Edition and 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, which, if you click 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 only displayed if you have an e-mail client running on your computer that is capable of updating the Welcome screen. Currently, there are only two applications that support this feature, Microsoft Outlook Express and Windows Messenger.

MORE INFORMATION
WARNING : Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the “Changing Keys and Values” Help topic in Registry Editor (Regedit.exe) or the “Add and Delete Information in the Registry” and “Edit Registry Data” Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).

This e-mail hyperlink is only displayed if the e-mail client that your computer is running populates the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UnreadMail
You cannot disable this feature in the user interface nor can you configure the Welcome Screen to populate the unread message count from only a particular e-mail application. For example, you do not want your e-mail messages from UserID @hotmail.com displayed on the Welcome screen. However, to work around this behavior, you can set the permissions on the following registry key to read-only for the System account:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UnreadMail
When the application attempts to update the registry key as new mail arrives, it will not have sufficient permission to do so and the Welcome Screen will not be updated.
Start Registry Editor (Regedit).

Navigate to the following folder in the registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UnreadMail
Right-click the UnreadMail folder, and then click Permissions .

Click the System account, and then check the Deny check box for full control

Click OK .

Quit Registry Editor.

To block only one of the e-mail clients from updating the Welcome screen, permissions to the registry key under “UnreadMail” specifying the e-mail account must have System permissions set to read-only. For example, you have the two following registry keys under the UnreadMail key:
UserID @msn.com
UserID @hotmail.com
To block UserID @msn.com from being displayed on the screen and to retain UserID @hotmail.com, set the permissions on the UserID @msn.com key:
Start Registry Editor (Regedit).

Navigate to the following folder in the registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UnreadMail
Expand the UnreadMail folder.

Click the e-mail provider that you do not want to be displayed on the Welcome screen.

Right-click the folder, and then click Permissions .

Click the System account, and then check the Deny check box for full control

Click OK .

Quit Registry Editor.:rolleyes:
