The much-talked update for Windows 8.1 and the first sign of the fusion of modern and desktop interfaces, Windows 8.1 Update 1 will be available on March 11, 2014 (Patch Tuesday) through Windows Update.

According to previous rumors, the update was to be announced at the Build 2014 developer conference in early April. The sources contacted by ZDNet’s Mary Jo Foley, instead, confirm the Patch Tuesday of March as the release date.

A few days ago, few screenshots were published, showing the Modern app tile on the taskbar. Paul Thurrott of had also hinted that the app would be closed using the window buttons in the title bar, such as the desktop applications. Now again, some new screenshots, coming from the Russian leaker Wzor, reveal two interesting features that Microsoft will integrate into Windows 8.1 Update 1, specifically designed for users who prefer to use the mouse over the touch interface.

When you select a tile on the Start screen with a right-click, the command bar pops up at the bottom of the screen. In the upgrade, this [command bar] will only work on touch devices (tap and hold), while a context menu will appear – against mouse events — that consists options to remove the tile from the Start screen, pin the tile on the taskbar, change the size of the tile and uninstall the app.

The second new feature will solve one of the major flaws of Windows 8.1. Finally, Microsoft will put the power button on the Start screen (top right), next to the new search button. You no longer have to look for the button in the Charms bar.

Apart from this, the Redmond Company is also optimizing the operating system in order to reduce the memory footprint and disk space.

Now, the Build 2014 conference, scheduled for April 2 to 4 in San Francisco, would be focused on Windows Phone 8.1 (available by the end of the same month) and, perhaps, on Windows 9 (available in April 2015).
