According to NetMarketShare's latest statistics, Windows 10's market share has finally overtaken Windows 7. The Steam userbase hit this critical crossover point in 2016, and Statcounter claims that Windows 10 usage was higher this time last year. But NetMarketShare claims they measure market share, not raw traffic colume like Statcounter. Together, Windows 8 and 8.1 only account for about 6% of the market, while the various versions of OSX command a 10.65% market share, and Linux accounts for a mere 2.78%.
