"If your computer runs Windows, and is attached to the Internet, it carries on a continuing dialog with Microsoft, without your knowledge or permission."
I am afraid that is not correct. There is a point when one is asked if it is OK that the PC is checked over by MS if you say no, it won't happen. If you have agreed in the past it is also possible to remove permission restrictively.
To answer the OP's question. You buy a license or go to China.
