Microsoft says Windows 10 is now running on more than 200 million computers and other devices, five months after the new software was released.
The company says Windows 10 is seeing faster adoption than earlier Windows versions, with 40 percent of Windows 10 devices activated since the year-end shopping season started after Thanksgiving.
Microsoft made the announcement in a blog post as PC makers prepare to unveil new Windows 10 products at the CES gadget show in Las Vegas this week.
Microsoft is hoping the new software – which runs on personal computers, tablets, game consoles and other gadgets – will help it regain ground as it battles Apple and Google for consumer loyalty. It hopes to have Windows 10 on a billion devices in three years.
But it has a way to go. Analysts say the most common PC operating system is still Windows 7, which was released more than six years ago and lacks capabilities of newer releases.
