At the Mobile World Congress in Barcelona, Microsoft officially talked about the update and some of its features, referring it as “Spring Update.” According to the Russian leaker WZor, The RTM Build has been compiled on February 21 and digitally signed off on February 26. The update package is identified by KB2919355, weighing about 700 MB (64-bit version). Along with the Update 1, the Redmond developers will also be releasing some other minor updates, as well.


The Update 1 for Windows 8.1 concerns about desktop users especially, who prefer to use mice and keyboard rather than touch screen. The improvements introduced with the Spring update include the title bar with close and minimize buttons for Modern apps; ability to pin the apps the taskbar, right-click context menu for mouse events on Start screen.


This also includes boot to desktop feature (only for non-touch devices), thus bypassing the Start screen.

To encourage OEMs, Microsoft has already reduced the licensing costs for the products under $250.

As per previous reports, the Windows 8.1 Update 1 will be available on April 2 for MSDN subscribers, followed by the general availability on April 8.
