WASHINGTON: Microsoft began rolling out its Windows 10 operating system Wednesday, aiming to revive the tech giant’s fortunes, especially in mobile and the “Internet of Things.”

The stakes are high for Microsoft as it pushes out the new operating system for both traditional computers and mobile devices such as tablets and smartphones.

The US tech giant is hoping the new system can help it gain traction in mobile, where it lags behind Google Android and Apple iOS.

“Our vision was one platform, one store, and one experience that extends across the broadest range of devices from the smallest screens to the largest screens to no screens at all,” said Microsoft executive vice president for Windows Terry Myerson in a blog post.

Forrester Research analyst Frank Gillett said Microsoft faces a tough task in catching up with Google and Apple in the mobile space.

“Microsoft will face a long road ahead to gain Windows share in mobile,” he said.
