I'm not saying leaving Messenger enabled is always better. I'm just saying
that it's more of a matter of personal opinion where there is room for
arguing either side successfully. Personally it seems sensible to me to
disable the Messenger service in work environments [for better security] and
not bother telling home users here to disable it [for convenience]. You're
right that future Messenger vulnerabilities are possible or even likely, but
for most of the home users you meet here, you only get about 30 minutes of
their attention max before they get bored and wander off to do something
else. So, you tend to go for security instructions that get you the most
benefit with the least effort. For me, that means that *if* I decide to
mention disabling the Messenger service here, I usually state that doing so
is optional. Or, I might not mention it at all, for fear that they might
latch onto that and somehow end up skipping the step where they install a
firewall.
