For those of us without MS certification, does the Messenger service have 
any function beyond allowing pop ups, and is there a way for a home user to 
simply delete the Messenger service from their at home XP, or at least 
knock it out (renaming perhaps?) while still maintaining functionality of 
their XP machine for spreadsheets, WP and web surfing?

Note that the "Messenger" vulnerability is NOT in Windows Messenger or
MSN Messenger...it's in the Windows Messenger SERVICE.

The service is installed and running by default in NT / 2K / XP, and is
exploitable via RPC (135) and/or NetBIOS (137 - 139 / 445).

It's definitely a worm-candidate, though I have not seen anything about
exploits in the wild.
