It installs the ability to have MS’ server query your machine for illegal software. But, remember, this is MS.
The big question most have, including myself, is, if I already activated my copy, why would I want to allow them into my computer at will?
If it detects a “tampered” file, activation “error”, or activation exploit, it will cripple your machine and direct you to call MS for further instructions.
If one were to have an activation error, which I have had with XP, you would not be activated and you would receive a message to call MS to remedy the error. So, why do I need a backdoor for MS to come in with, after I’ve already had a successful activation?
As for “tampered” with files and “exploits”, that’s what Security Essentials says it does already, so no need to allow MS carte blanche access.
In essence, this will allow MS to enter your PC, without your knowing or consent, and give them the power to shut your PC down. One can only imagine what else they will do, as they would now have the ability to do anything they desire.
Are there any features that won't install if we don't have this update?
Is there a way to have your firewall keep MS from “phoning home?”
