Blocked INCORRECTLY!!! Did you test some url, like this one:

It should NOT work
P.S.
Just checked and you should try checking your blocking on PC. Here same urls blocked and NO J UPDATE

Okay, so I was able to take it back to the store and get a new one!

I have not connected it to the network and I will not until I am sure I have blocked updates.
I have a thread with screenshots documenting my attempts at this so far, and it is located here:

So far it seems I can add a bogus DNS entry for msecnd.net, but it does not allow me add *.msecnd.net so it is not working properly. What might work would be if I manually blocked ALL of the hosts, like abcd.msecnd.net - can you please post a list of the hosts and I can test it?
