Windows 10's global growth slowed in December, but the operating system ended 2016 on more than a quarter of the world's Windows personal computers.
But in the U.S. Windows 10 continued to gain ground at a consistent clip. By year's end, it powered more than a third of all Windows PCs there.
According to analytics vendor Net Applications, Windows 10 gained six-tenths of a percentage point of user share last month, ending on 24.4% of all personal computers. However, Windows 10 ran 26.6% of all Windows machines: The difference between the user share of all PCs and only those running Windows stems from the fact that Windows powers 92% of all personal computers, not 100%.
