Screenshots of Microsoft’s next Windows 8 update, expected to be named 8.1 Update 1, have surfaced recently, and reports suggest it may be released in March. ZDNet reports that Microsoft is targeting a March 11th release date for the update, the same day the company releases its monthly security patches. While Microsoft has still not acknowledged Windows 8.1 Update 1 officially, many had expected the company to detail it at the upcoming Build developers conference in April. While Microsoft is looking to merge the desktop and Metro worlds a little more closely in future updates, Windows 8.1 Update 1 simply includes smaller refinements towards any significant changes that may arrive in Windows 9.
