I for one actually fell for this and already installed this "Patch" I will be uninstalling MS media player to never install it again.

"Reasonable efforts to post notices" somewhere on the Web. I think it"s clear from the wording that MS has absolutely no intention of bringing this behavior to our attention.
Instead, Microsoft has just assumed the right to attack your computer and surreptitiously install code of its choosing. You will not be warned; you will not be offered an opportunity examine the download or refuse it. MS will simply connect remotely and install what it will, or install it secretly when you contact them.
Curse your black heart, Bill Gates!! Will your insidious schemes never end??
