Uninstall and remove MSN messenger
It's not that difficult to remove the pesky little pile-on of a software: MSN Messenger!
Let us keep it simple. First, make sure you have exited MSN messenger and unsinstalled any MSN Messenger related entry from Control Panel (START –> CONTROL PANEL –> ADD OR REMOVE PROGRAMS).
Then, START –> RUN the following command:
Done. That should remove it. If it doesn't, check some more round-about and cumbersome ways from Microsoft that involve the Windows registry.

. This can be very simply achieved by doing the following:
(1) In Start –> Run, enter:
(2) In the "Advanced Tab" look for "Manage Passwords", which takes care of all the .Net passport passwords on your machine. You can also change the setting to not save any from this point on. Read this useful comment below (August 2005) for a solution that also works.
To disable the storage of these passwords altogether, follow the handy instructions here: WinGuides instructions.
[Thanks to Jessica below, comment #185] If you're getting the pesky "Signing into MSN messenger failed because the service is temporarily unavailable. Please try again later 800b0001" error, then follow these steps:
Open start menu and click RUN. Then individually type in the codes below and press Enter:
regsvr32 Initpki.dll [may take ~30 seconds, don't worry]
After executing these commands one by one, it should work.
This is usually because of a firewall preventing your MSN from connecting to the Internet, even before sign-on process begins. Make sure your firewall (Zone Alarm, Norton anti-virus package, etc) are allowing MSN Messenger.
