Well, when you turn on Windows Update you give Microsoft permission to install software on your mission without asking you.
That’s why I don’t do that. However, even for those who do, I don’t think it passes the “reasonable man” test to assume they’re consenting to having their OS stolen vs. typical Windows Update stuff like bug fixes, driver additions, etc.,
And besides, I believe even those who set the WU options for “download but don’t install, ask me” are getting herded/buffaloed/tricked into installing WX. You definitely can’t say they consented to updates without further consent.
