Microsoft: More than 14M devices running Windows 10

Microsoft says more than 14 million devices are running its Windows 10 operating software since it was released for download on Wednesday.

In a statement Friday, Yusuf Mehdi, corporate vice president of Microsoft's Windows and devices group, says the company has seen "unprecedented demand" for Windows 10.

"It has been an incredible 24 hours for Windows and our fans," said Mehdi.

Among the key features arriving with Windows 10: the addition of digital voice assistant Cortana, a new Web browser called Microsoft Edge and the ability to stream games from the Xbox One video game console to a Windows 10 PC.

The operating system is one of the biggest product launches under CEO Satya Nadella, who took over the top role at Microsoft last year. Under Nadella, Microsoft has shifted its focus to the growing cloud computing market and mobile.
