Thanks to Twitter user WalkingCat who has discovered several references for Windows 10 latest Version i.e. 1703 in the latest test versions of Microsoft's operating system.
This reference by WalkingCat gives a strong idea about the year and month of a release. This claim is trustworthy because Microsoft has previously installed same codes for its Operating System Update (1607) released in July last year.
For those wandering whether a 1703 Redstone 2 target implies anything about dates for Microsoft's Build 2017 event, it is not believed so. Microsoft doesn't need to include this new release of update in annual developer show. Developers in company are already working with early versions of Windows 10 that releases on a regular basis.
ZDNet has a good experience about proving Microsoft rumours right. The site has confirmed that March 2017 is "indeed the current ship target for Windows 10 Redstone 2."
Microsoft is also having an event on 26 October, where the launch of Surface Desktop might happen. Also they might even discuss about the update of Windows 10. Microsoft is planning for a "HomeHub" feature in coming Windows 10 update that will manage smart devices.
The Anniversary Update for Surface Hub includes simultaneous pen/touch support; inking support; Flash support for Edge, OneDrive and Photos apps, preloaded PowerBI and more.
Microsoft has also started testing some new features of Windows 10 with Windows Insiders; most of the changes have been fairly minor so far. Company is also planning to bring a blue light reduction feature to Windows 10, along with improvements to Cortana that will help in filling the gap between mobile devices and PCs.
