As Microsoft rolled out its much-anticipated Windows 10 operating system (OS) in 190 countries as a free upgrade on Wednesday, experts and commentators mostly gave it a thumbs-up.
Microsoft has described Windows 10 as "more personal and productive, with voice, pen and gesture inputs for natural interaction with PCs". It is designed to work with Office and Skype and allows users to switch between apps.
In an interview with the website Ozy.com, Microsoft CEO Satya Nadella said modern devices from smartphones to wearables, glasses and holographic computing all need an operating system, and that's why Windows remains absolutely relevant.
"All of these devices need an operating system, but do they need an individual operating system. They need a consistent experience to come across all of them. That's what Windows 10 is," Nadella said.

The new OS follows Windows 8, which launched in 2012 to severe criticism from users. The previous OS introduced the concept of "live tiles" in an effort to make it touch-friendly, but lost out on desktop usability in the process.
However, critics say Windows 10 has overcome those flaws.
Writing in the popular technology website Wired, David Pierce wrote: "Windows 8 was full of jarring movements, from full-screen app to full-screen settings to full-screen Start; unless you knew the complicated gestures and keyboard shortcuts, getting around was a chore. Now, there are multiple ways to do almost anything, and very few things you have to know."
He added: "It's free, it's easy, and it's a huge improvement on whatever version you're using."
The review further said, "The design is cleaner and flatter, with heavier contrast between icons and backgrounds and a slightly darker overall look. It's more consistent, too, as if Microsoft's designers finally made it deep into the menus. But it's the same Windows you've always known. Start Menu and everything."
Similarly, CNET too praised the new OS in its review.
"The new OS combines the best bits of old and new Windows features into a cohesive package, while correcting nearly all of the missteps of Windows 8," it said.
Talking about features available in Windows 10, the review said: "The Start menu in Windows 10 is admission that Windows 8 maybe have been a bit too forward thinking. But Microsoft hasn't abandoned that vision of unifying all manner of devices under a single operating system: Continuum in Windows 10 is the latest attempt to bridge the gap between touch and non-touch devices, and this time it doesn't force us to relearn how to work with our PCs."
Walt Mossberg, writing on recode.net, called Windows 10 a "rescue mission" by Microsoft, aimed to "fully backpedal from its 2012 predecessor, Windows 8".
Popular technology news website The Verge said Windows 10's built-in apps are a great complement to the OS.
