The latest update for Microsoft’s Windows 8.1 operating system has made its way online more than a month before its intended launch date.

The update includes plenty of improvements, including a new title bar for Windows 8 apps that lets you open, close, and arrange apps with your mouse. Apparently, the change is intended to make things easier to navigate while using the desktop experience.

There are also some big changes to the start screen, which now gives you the option of right-clicking your mouse button on live tiles to get a new menu of view options (resizing, closing, etc.). Microsoft has also added the ability to turn off your computer or log out of an account directly from the start screen.

The leaked Windows 8.1 build was done January 14, according to a report by The Verge. That means this version of the update might not be entirely finished, with Microsoft still planning to add further UI and feature changes ahead of its official launch date.
