Microsoft will get your "Internet protocol address, the type of operating system, browser and name and version of the software you are using, and the language code of the device where you installed the software." But all they really need is your IP address.
Oh No! Microsoft will have my IP Address, OS, Browser, Name and version of the software I'm using, and the language I use!
Oh wait, every website I've ever visited has the potential to have that information.
IP address, I can somewhat understand. But the other stuff? Yes, I'm among the millions that use Firefox, Windows XP, and speak English. Tell me how that is going to help anyone identify me? Even the IP address I use isn't static. Just look at how much trouble the RIAA has had tracking down users via IP address. And honestly, of the millions upon millions of people that use Windows do you really think that Microsoft is going to come after YOU? If you are that paranoid perhaps you should disconnect your computer and put on your tin foil hat. It'll free up some space on the tubes for the rest of us.
