Microsoft says its’ new Windows 10 operating system is now running on more than 14 million computers, two days after the software was released as a free download.

That’s a far cry from the company’s goal of getting Windows 10 onto a billion devices within three years. Microsoft says it’s releasing the software in waves to make sure downloads go smoothly.

Windows 10 bridges the gap between PCs and tablets without alienating anyone. 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. Windows 10 delivers a refined, vastly improved vision for the future of computing with an operating system that’s equally at home on tablets and traditional PCs — and it’s a free upgrade for most users.

Windows 10 brings much awaited multiple desktop facility. User can put same types of apps in each of the desktops, e.g. surfing internet – all internet tabs open in one desktop, all office documents open in another window. User can easily switch between these windows making multitasking more easily.

Meanwhile, for businesses, the major change is that mobile device management style separation for work and personal apps will be a feature of all devices running Windows 10, from smartphones through to tablets and PCs.
