Microsoft says its new operating system, Windows 10 is running on more than 75 million computers, tablets and other devices less than a month since the operating system was released.
The software giant is however hoping to get the software installed on a billion devices over the next three years.
Microsoft is also hoping Windows 10 will help it rebuild loyalty among users who are increasingly relying on tablet, smartphones and other devices.
Microsoft is offering Windows 10 as a free download for many computer owners. The free upgrades probably account for the bulk of the 75 million devices now using Windows 10.
