According to an anonymous Microsoft insider, ZDNet has broken the news that Windows 8.1's next update should launch on March 11th of this year, which we're sure is no coincidence that the update will be releasing just a few weeks before Windows Phone 8.1 releases. Perhaps we'll see some cross-platform features bundled into this update alongside some performance, UI, and optimization tweaks.
Details of the update are still unclear, but it's expected that this update will include some technical tweaks that will improve the operating system's memory footprint as well as the required disk-space for installation. There are also a handful of changes to the Metro UI functions, including the ability to "pin" apps to your start page, as well as some general UI improvements for PC users that rely on the mouse for input commands. Many fans are hopeful that the official revival of Microsoft's traditional Start menu will return in some form with this update. If not, it's like we'll see its return next April with the rumored Windows 9 unveiling. Time will tell.
