Microsoft is also doing away with Windows Media Center in Windows 10, which means that anyone with a Windows 7 or Windows 8 PC will have that software removed when they upgrade. Microsoft is also doing away with built-in DVD playback software, so users will have to get their own if they want to watch a movie or TV show on a physical disc.
Not every device will be compatible with the latest features available in the update, either. In order to use the facial or iris recognition features of Windows Hello, users will need a specialized illuminated infrared camera. (Surprisingly, neither the Surface 3 nor the Surface Pro 3 features such a camera.) Cortana, meanwhile, only works in the U.S., U.K., China, France, Italy, Germany and Spain.
Overall, the low barrier to entry seems tailor-made to help Microsoft meet its goal of having one billion devices running Windows 10 by the end of the company's 2018 fiscal year. Getting as many devices as possible on Windows 10 is important, since Microsoft is pushing developers to create new applications for the Universal Windows App Platform and sell them through the Windows Store. In order to motivate developers, Microsoft will need plenty of Windows 10 users.
