Microsoft’s first update to Windows 8.1 has leaked today 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.
