Microsoft finished 2018 by hitting another major milestone.

Windows 10, the company's newest desktop operating system, is now the most popular in the world. It surpassed 9-year-old Windows 7, according to Net Applicationsvia The Verge.

Windows 10 now holds more than 39 percent of the marketshare for desktop operating systems as of December. Windows 7 only makes up less than 37 percent.

The report also claims that more than 700 million devices now run on Windows 10. These devices include PC, Xbox One, tablets, and phones.

Microsoft ended most support for Windows 7 in 2015. Extended support for the OS officially ends in 2020. The company has urged users to upgrade and Windows 7’s market share has experienced a steady decline ever since.

Windows 10 was released in 2015meaning it took about three and a half years for Microsoft to achieve this record.

While owning the desktop OS market, Microsoft has still fallen well short of its original goal from when Windows 10 was first released. The computer giant had originally aimedfor Windows 10 to be installed on one billion devices within a three year timeframe.

Regardless, even with a few stumbles, Microsoft had quite a 2018and Windows 10 certainly played a part.
