According to the results, in December, Windows 10 was installed by 39.22% of users while Windows 7 followed with 36.90% and Windows 8.1 with 4.45%. To provide context, in January of the same year, Windows 10 was only installed on 34.29% of users' computers with Windows 7 being on 42.39% and Windows 8.1 on 5.56%.
With Windows 7 and 8.1 usage shrinking throughout the year, it's safe to assume that at least some of the growth in Windows 10 usage was due to people upgrading from older versions of the Windows operating system.
Apple's Mac OS X 10.13 came in behind Windows 7, 8.1, and 10 in almost every month with the exception of June, July, August, and September when it briefly overtook Windows 8.1 for third position.
