How to Restore the Existing Blocked Senders List and Other Mail Rules to Function on the Newly Installed Operating System

1.	Open Outlook Express on the new computer, and complete the Internet Connection Wizard to set up your Identity and account information. If you had multiple identities in the previous installation, complete these steps for each Identity. To do this:
2.	Click Start, and then click Run.
3.	In the Open box, type notepad.exe.
4.	Click Open on the File menu, and then locate the Block Senders.reg file that you created.
5.	In the second line of text, select the text after "HKEY_CURRENT_USER\Identity\" that includes the braces {}. On the Edit menu, click Copy to copy this text to the Microsoft Windows Clipboard.
6.	On the Edit menu, click Replace. Click your pointer in the Find what box, and then click Paste on the Edit menu to paste the text into that box. Do not close the Notepad application until you are directed to do so later in this process.
7.	Start Registry Editor on the new computer (as in step 1 of "The Blocked Senders List" section), and locate the HKEY_Current_User\Identities folder. Double-click the User ID key in the right pane, and then click the Value data.
8.	Press CTRL+C to copy that value to the Windows Clipboard. Click Cancel to close the Edit String dialog box, and then close Registry Editor.
9.	In Notepad, click your point in the Replace with box, and press CTRL+V to paste the text. Click Replace All to replace all instances of the text strings.
10.	Scroll through the entire list to make sure that all registry keys have the new text string, rather than the old string. On the File menu, click Save, and then close Notepad.
