Microsoft held a quick event to let media know about their new product the 'Windows 10' which will be coming by the year end. The event was held at Microsoft's headquarters in Redmond, Washington. The key talking points of the event were : 1. Free Upgrade Windows 10 will be a free upgrade to anybody with Windows 7 or later, for one year. There was also a lot of talk about "Windows as a service," but that does not mean you'll pay for a subscription to Windows, like you do with Office 365. It just means Microsoft will push updates to the platform more frequently, and you'll get them in the background. That's not really new. 2. Gaming The Windows 10 OS will have a Xbox app that will let you connect with Xbox Live and play with other users online and will also let you pause and resume games. It will also enable you to stream games from Xbox One to your Windows 10 device in your home. 3. Holograms The coolest thing was a set of new products that will let people see holographic images. The hardware is called Microsoft HoloLens and looks a lot like Google Glass. There are also software tools within Windows 10 that will let programmers create apps that use holograms. 4. Mobile This was probably the most lackluster part of the presentation. There will be a version of Windows 10 for smartphones, but it looks and feels a lot like Windows Phone, which has been around for four years. The goal, Microsoft says, is to create experiences that span different platforms. So, for example, you'll be able to start doing a task on your PC than transition to your phone. But Windows Phone has had a hard time gaining market share, and nothing Microsoft said today will change that. 5. Developers Microsoft also talked a lot about Universal apps, which is a new way of building applications that can easily be ported from PCs to mobile and Xbox devices. It's not quite "write once, run anywhere," but it's a lot closer than past versions of Microsoft products. The goal? To convince Microsoft's large base of Windows PC developers to move their apps over to Microsoft's newer mobile platforms, which will hopefully close the app gap versus Android and Apple's iOS.
