Just say "no" to Windows??
I remember when Microsoft turned all of the backgrounds black. Because, like, pirated, right? Yes, years back, Microsoft decided that it would be cute to point out who was running an "unlicensed" installation of Windows. And sooooo many screens in the Chinese government wound up with black backgrounds. And they couldn't change that setting for 24 hours.
This new Chinese move also opens up the question: how are they going to dispose of all the American computers? Sell them, or scrap them out?
