The second update coming for Windows 10 is codenamed Redstone, and is a larger update compared to Threshold 2. Redstone will be what Windows 8.1 was to Windows 8 essentially, bringing much needed changes and improvements to the feature-set and design of Windows 10. Redstone is scheduled to launch around a year after Windows 10 did, and is pretty much ‘next' version of Windows.

Over the past couple of months, Microsoft has been in the planning phase of Redstone, and although it's too early to begin detailing all the features they are planning, we can confirm that Redstone has now entered early development, and has been for a few weeks, meaning engineers are now beginning to lay-down code. Since we're several months away from RTM however, not a lot differs from these current builds.
