Microsoft has been moving/changing Windowsupdate.microsoft.com for
the last week or so. The problems have been covered extensively
in other forums.
Although microsoft technicians have messed up access filters on its
routers in the past, I believe this is just them blocking some packets
used by the standard traceroute. If you are having other problems
with windowsupdate, I think they are unrelated to traceroute.
