Stop Windows Messenger from Auto-Starting

f you're not a big fan of Windows Messenger, you can simply delete the following Registry Key:
HKEY_CURRENT_USER\Software\Microsoft\Win

dows\CurrentVersion\Run\MSMSGS

After doing so, Windows Messenger will no longer start when you logon. However, if you run any
program that requests the use of Windows Messenger (such as Outlook Express), the registry key
will be re-created, and Windows Messenger will load on Startup again.
