After several years, the current version of Windows has overtaken the previous king of the operating system market.
According to the NetApplications.com-operated NetMarketShare usage statistics website, Windows 10 has overtaken Windows 7 in worldwide usage in December of 2018. This comes three-and-a-half years after the release of Windows 10. To quote VentureBeat's succinct analysis: "Windows 10 had 38.14 percent market share in November and gained 1.08 percentage points in December to hit 39.22 percent."
With this move, however, still belies a fact set to become more troubling: As of December of 2018, nearly 37 percent of all Internet-connected computer users still actively choose to use Windows 7 over the later released Windows 8 and Windows 10. This is despite the fact that Windows 7 will reach its end of life in January of 2020. For users that either cannot or will not opt into the extended support timeline for Windows 7 for enterprise and education, this will pose a danger of incompatibility with future versions of their most used apps, not to mention potential security vulnerabilities.
As far as other versions of Windows in terms of market share, Windows Vista no longer has statistically significant usage according to NetMarketShare, with a .2 percent market share for December of 2018. Windows XP, on the other hand, stands at 4.54 percent. Windows XP stopped receiving updates in April of 2014.
