WinXP not vulnerable? You should upgrade your OS (which, of course, you all should do anyway so as to send more money to the Great Monopoly In The Sky) to get rid of this security hole.
Oh, wait. Going to WinXP isn't an "upgrade."
You should upgrade your OS to something not produced by the Great Monopoly In The Sky for better security...
Admins: Move to Oh Pun? ;-)
