Windows 10 on 1 billion devices in two to three years

Terry Myerson, Microsoft’s executive vice president of operating systems, set a huge goal for the company: Windows 10 on 1 billion devices “in two to three years.” This is a promise to developers that if they invest in Microsoft’s upcoming operating system, they will have access to a massive userbase.

I owned Windows Vista and Windows 8, when Windows 10 launched; does that mean I get a free upgrade for both OS versions? If the answer is yes, I’m already in the 1 billion devices statistic.

I wonder how big can Microsoft be with free offerings. You know, users love free stuff. I love free stuff. What about you?
