Microsoft Windows 10 is a next-generation operating system that looks like it will do a far better job at bridging the gap between desktop and mobile systems compared to its predecessors. Windows 10 will include new platforms for phones, tablets and PCs which will be available for free for a year for those upgrading from Windows 8.1.
One aspect of Microsoft Windows 10, which is sure to be greeted with jubilation by many, is the death of the sluggish Internet Explorer. The new system will come with a next-generation web browser called Project Spartan.
Another major talking point is the integration of Cortana -- Microsoft's answer to Apple's Siri -- into computer and tablet operations for the first time. Cortana will help you compose emails from speech and fill in data gaps much like Google Now by making proactive suggestions.
Windows 10 is expected to launch later in 2015 with new computers and phones from Microsoft and partner companies.
