Microsoft’s first update to Windows 8.1 has leaked on Sunday on various file-sharing websites ahead of its March debut. The early build includes a number of changes that Microsoft is making to improve the keyboard and mouse experience in Windows 8.1. The most obvious change is a new title bar for Microsoft’s Windows 8-style apps, allowing you to close, minimize, and snap apps to appear side by side with a mouse. It occupies a small amount of space at the top of all "Metro" apps, and it appears to be included as more of a helpful option for mouse users to quickly navigate through apps. Similar improvements have also been made to the Start Screen, where right-clicking on Live Tiles now produces a context menu with options to resize, unpin, and more. Microsoft is also bringing the search button and a shutdown option straight onto the Windows 8.1 Start Screen with this update. Read the full story at The Verge.
