According to a report published by NetMarketShare, the Windows 10 OS has roughly reached 24% of the Market share in the month of November. The Growth for the Windows 10 OS has slowed down once Microsoft ended the Free Upgrade option.
The Market Share of Windows 10 is still below as compared to the Market Share of Windows 7 which is around 44% since lot of users are still comfortable in using the Old version  of Windows as it is compatible to most of the apps and features.
Microsoft’s aims of Windows 10 to work on all majority devices to reach more than a billion users within 5 years of its launch has actually taken a hit due to the Market Share of Windows Phone being below 1% compared to Android and iOS and also the slowdown in the PC industry.
