but the update is installed in the background with the user knowing almost nothing
then retreaving information
microsoft has no right to do that
Lets see if you set your computer to notify you when updates are available and let you decid if you want to install you can prevent all of this.
I have yet to have a Microsoft update install on my PC with out me knowing it but if I set my PC to automatically download and install updates then it is "Shame on me" if the system sends out my information not "Shame on Microsoft" for getting the info. I blindly let my system update so I have no right to complain over what the updates do.
User License Agreements are in place to let you know what the company can do and also whatt your rights are so you might want to start caring about them.
