Windows 10 replaces XP as the second most-used OS in the world:

Market analyst firm Net Applications has revealed new data showing that Windows 10 adoption rate is going stronger than the last few months of 2015. Going up from 9.96 percent in December, Windows 10 is now on powering over 11.85 percent of devices in January, a growth of 1.89 percent. After the initial launch hype in July-August, the OS has managed a growth rate of approximately 1 percent every month. January saw an accelerated adoption rate, possibly because of the post-holiday hike in new devices.
The new operating system has not only seen the biggest growth after August, but also has managed to surpass Windows XP to become the second most-used OS in the world. The new figures reveal that Windows 10 is now running on 11.85 percent of devices, managing to win over Windows XP which is running on 11.42 percent of devices worldwide.
