Microsoft's Windows 10 has been available to consumers for nearly a year, so it's no surprise that software has seen impressive uptake.
Windows 10 now has 270 million monthly active users. That's a boost on the 200 million devices using the operating system, as reported by Microsoft in January this year.
The announcement came courtesy of Terry Myerson, Executive VP of Windows and Devices, speaking at today's Microsoft Build conference in San Francisco
"[Windows 10] already being actively used by over 270 million people," said Myerson, speaking to developers and press at the event. "Customers are more engaged than ever before, spending over 75 billion hours on Windows 10."
