Famed Russian software leaker, WZor, has tweeted in response to rumours of an April 2015 launch of Windows 9, that Microsoft is on track to release the final bits to manufacturing by October 2014.



From Neowin:

Windows 9 is expected to advance the Modern UI further as "Metro 2.0," to be more mature and usable. Although we have heard that Microsoft won't be making pre-alpha builds available to developers at the upcoming BUILD 2014 in April, we can expect to hear more about the future operating system directly from the company.

  Windows 9 could reach RTM as early as October
