From a report by long time Microsoft watcher Brad Sams on Petri.com: With 2016 now behind us, we can take a look at how far Windows 10 has come thanks to usage-share with statistics from Net Marketshare. At the end of December for 2016, Windows 10 is installed on roughly 24.5% of devices whereas, at the end of 2015, the OS was only installed on around 10% of machines. During the same period, Windows 7 declined from 55.68% to 48.34%, Windows 8.1 usage dropped from 10.3% to 6.9% and XP dropped slightly from 11% to about 9%. Also, released alongside Windows 10, is the company's new browser, Edge. While the market share of the desktop OS has grown steadily, Edge has not performed as well. At the end of 2015, Edge obtained a market share of 2.79% and at the end of 2016, it has climbed to 5.33%. But, Chrome, which had a market share of 32.33% at the end of 2015 now commands 56.43% of the market. During the same period, Internet Explorer dropped from 46.32% in 2015 to 20.84% in 2016.
