Microsoft is expected to release Windows 8.1 Update 1 for free, either next month or early April. It won’t be as extensive an update in terms of features and codebase as Windows 8.1 was for Windows 8. Instead, it will add functions that appear to be aimed at improving the experience for users who interact with the OS through a keyboard and mouse (or touchpad). We acquired a leaked build of Update 1. Here are the new functions it will add to Windows 8.1 (and the rumored ones that it probably will not). Of course, keep in mind things may change (i.e. features added, removed or revised) before this update is officially released.
