Re: The BBC called, they want their technology journalist back.
It's not a "fact". It's wrong, pure and simple. There are many Win7 machines where GWX has been disabled.
And as a bit of hyperbole it's unnecessary. People who have disabled GWX generally have done so because they're annoyed (or worse) by it; so it would have sufficed to note that most Win7 systems suffer from GWX nagging, and if they don't, it's because someone has gone to the trouble of disabling the damned thing.
