Within just six months of its official rollout which commenced on 29 July, 2015, Microsoft's new Windows operating system is now running on more than 200 million PCs worldwide. The adoption of Windows 10 is quite fast, outpacing Windows 7 by 140% and Windows 8 by 400%, says the Redmond-based company.

Within 24 hours of its rollout, the OS was already running on 14 million units. In October 2015, Microsoft's Terry Myerson confirmed that 110 million units were on the new Windows version. Outside Microsoft, even analysts believe that Windows 10 is the most installed version of Windows ever.

While sharing fun facts about Windows 10, Yusuf Mehdi, corporate vice-president of Windows and Devices Group at Microsoft, said there is also a surge in demand for the new Windows version among enterprise and education consumers. Windows 10 is now on 22 million devices across enterprise and education consumers.
