Yeah, I rebooted, as per the instructions. Twice, to be sure. Oh well.
Regarding the article, I suppose this was a minor issue at the time of the writing (almost two years ago), I really don't think that the PC Mag "security watch special" referenced is all that relevant today.
If it was, I'm sure we'd have heard much more from other reporting venues about this exploit being used, or about the exploit (which appears to me to be nothing more than a proof-of-concept possiblity found by the writers), and then being patched by MS. Also to keep in mind, this article was written when all the FUD about upgrading to XP SP2 was going around. So I take it a grain of salt.
Frankly, it offends my senses as a tinkerer of computers and mechanical stuff to shut off a warning light because it happens to be somewhat annoying (doing things the speedy way), instead of finding the root cause and fixing it (doing things the right way). I suppose I must be alone in this contention, so off to hiding the notification I will have to go...
