How to log in to multiple MSN accounts simultaneously on one computer

Is there any way to login to multiple MSN accounts at the same time? For example, an account dedicated to work, a family friend to contact.

Method One: Fixit automatically repair.

Click the "Fix this problem" link in the file download dialog box, click "Run" and then follow the wizard.

Method two: do it yourself.

From the Start menu, click "Run" (or press the shortcut key combination "Win + R"), type the command regedit.exe, press Enter. Open the Registry Editor.

(If pop-up user account control window, please allow to continue)

If you are using a 32-bit operating system, navigate to the key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows Live \ Messenger

(If using a 64-bit operating system, navigate to the key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Microsoft \ Windows Live \ Messenger)

Right-click the blank space in the details window and right-click and select "New-Word Value."

Name the new value "MultipleInstances" and double-click it to assign a value of 1.

that's it. Exit the registry and log in to MSN again. Now we can log in with different accounts at the same time. As long as you like, you can even chat with yourself!
