And Microsoft really needs to nudge consumers into buying Windows 8 machines. More Windows 8 machines means more developers will want to write software for Windows 8, which will make more people want to buy it.
By the way, Microsoft also set an end-of-life of mainstream support for Windows 8 (including the latest version, Windows 8.1), for January 9, 2018.
