Microsoft has sold more than 200 million Windows 8 licences in 16 months. The figures see the firm's touch-centric operating system lagging behind 2009's Windows 7 in terms of sales over time, as Windows 8 struggles to top a 10 percent market share.
In a statement shared with V3, Microsoft said the figures include Windows 8 licences that ship with new PCs and tablets (OEM) as well as upgrades from older versions of Windows. It does not, however, include volume sales to enterprise customers.
"Windows 8 has surpassed 200 million licences sold, and we continue to see momentum," the statement said. "Windows is a central part of life for more than 1.5 billion people around the world, and we are looking forward to the future."
May 2013 was the last time Microsoft disclosed its Windows 8 sales figures, touting 100 million licences sold in the first six months on the market. By comparison, Windows 7 sold 240 million licences in its first year on shelves.
Recent figures from research firm NetMarketShare saw Windows 8 snatch 10 percent market share in the global operating system market, with the 13-year-old Windows XP also gaining market share slightly.
The sluggishness of Windows 8 adoption has been partially blamed on a slowdown of the traditional PC and laptop market, with demand falling by 10 percent in 2013.
The wholesale changes to the user interface in Windows 8 also meant consumers had to get used to a new way of working, which has reportedly put some of them off. PC manufacturers are now banking on future updates to the operating system as well as the arrival of Windows 9 to rekindle demand.
