Microsoft is set to host a large-scale event scheduled on January 21 and it is set to cover not just PCs and notebooks, but also how Windows 10 will improve the way smartphones, tablets and the Xbox One work.

Developers have already had a taste of Windows 10's capabilities and the most interesting and innovative new feature is something called Continuum.

It's a smart user interface that will automatically change based on what the user is doing. So, if the device is being used like a desktop computer -- keyboard and mouse -- it has the classic Windows feel, but lay a finger on the touch screen or, if it's a 2-in-1 device, remove the display from the keyboard, and everything instantly switches into a touchscreen input mode.

Windows 10 is also going to work across the whole ecosystem of Microsoft devices. The January event will be the clearest indication yet of how easy it will be to share documents or tasks across PCs and mobile devices.

Windows 10 may have new browser 'Spartan', Internet Explorer on way out

Internet Explorer, Microsoft's venerable but often despised web browser, may be on its way out, it has been claimed.

The new browser, codenamed at this point as Spartan, will be unveiled on January 21, in the company's hometown of Redmond, Washington, when Microsoft shows off Windows 10 for the first time.
Spartan may make its formal debut there, but the general release of Windows 10 is not expected until the fall, so it may come at a later date.
Thomas Nigro, a Microsoft Student Partner lead and developer of the modern version of VLC a media playing app, claimed on Twitter earlier this month that he heard Microsoft was building a brand-new browser.
"Ok so Microsoft is about to launch a new browser that's not Internet Explorer and will be the default browser in Windows 10. Wow," he tweeted.
Spartan will look and feel more like Chrome and Firefox, however, it will support extensions, reports said. The "lightweight" browser will be available on both desktop and mobile devices in Windows 10, they said.
