Yes, they used the bulletin to soft-pedal the description, but at the
same time I think they send a message about XP users being on shaky
ground. Just because they've got 4+ years of Extended Support Period
left doesn't mean they're going to get first-class treatment.

It's only "default" for people running XP standalone/consumer that are 
not even in a home network settings.

That kinda slices and dices that default down to a VERY narrow sub sub 
sub set of customer base.

(Bottom line, yes, the marketing team definitely got a hold of that 
bulletin)

and for which you have no intention of making a patch for, don't tell me
it's mitigated by ancient, unusable default firewall settings, and don't
withhold explicit details.  Say "THERE WILL BE NO PATCH, EVER.  HERE'S
EVERYTHING WE KNOW SO YOU CAN DETERMINE YOUR OWN RISK."  Also, don't say
'you can deploy firewall settings via group policy to mitigate exposure'
when the firewall obviously must be accepting network connections to get
the settings in the first place. If all it takes is any listening
service, then you have issues.  It's like telling me that "the solution
is to take the letter 'f' out of the word "solution."

Win7 to corporate customers by providing free XP VM technology and thus
play up how important XP is and how many companies still depend upon it
for business critical application compatibility, don't deploy that
technology in an other-than-default configuration that is subject to a
DoS exploit while downplaying the extent that the exploit may be
leveraged by saying that a "typical" default configuration mitigates it
while choosing not to ever patch it.    Seems like simple logic points
to me.
