Windows 10 launched on July 29, but Microsoft already has plans to release a major update to the OS around that same time in 2016. A new report says that early work on that update, code named "Redstone", has already begun at Microsoft.

According to WinBeta, "Redstone" will likely be as big of an update for Windows 10 as Windows 8.1 was for Windows 8., It added:

"Over the past couple of months, Microsoft has been in the planning phase of Redstone, and althoug (sic) 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."

Meanwhile, work continues on another, much smaller, update for Windows 10, under the code name "Threshold 2". This update is expected to be released later in 2015, and wll reportedly add a few previously announced features like extension support for Microsoft Edge and the official release of the new Messinging apps.
