It does mean they can do what they want with your system because the hardware and software are so closely linked. If Microsoft doesn't have the right to control your system then they can't sell you an operation system. That's what an OS does.
I also do not see why you think they have no right to your data. If you send them the data, they should be able to use it for whatever purpose they want that you agree to in the license. Assuming it's not illegal for some other reason, like credit card fraud.
I don't understand what principles people use to decide that they own all of their data and all data about themselves. It doesn't make sense to me.
