Microsoft have announced August 2nd for the Windows 10 anniversary update (Redstone) release of the OS. Microsoft let the cat out of the bag via a blank headline only post at the Microsoft News Center, expect a correct post later in the day.
The original version of Windows 10 launched July 29th with the release being available for Windows Insiders a few weeks before hand (July 16th). The anniversary update includes new Windows Inking, dark themes, Microsoft Edge Extensions and a new start menu. Insiders will probably get the build early again with the clue being no watermark after installing.
