Microsoft's Windows 8.1 update might not make any grandiose changes, but it looks as if it will offer some appreciated and start-up improvements. A new build with an unreleased upgrade in tow, has leaked online, offering risky types the chance to try it several weeks before its official release. As teased last month, the update will let you pin your apps alongside other programs on your desktop start bar. It sounds like a timesaving improvement, as before you'd have to labor through the Start screen to launch those aforementioned apps. Windows 8-styled apps also pick up a new bar with close, minimize and snap options available to click on, forgoing those keyboard shortcuts. Live Tiles now have contextual menus available with a right click, making them easier to resize, move (or remove). A new shutdown button, as leaked justlast week, also throws up a new drop-down menu for restarting, shutting down and sleep mode. This experimental build is apparently a three-week old one -- the real is expected to arrive next month.
