On August 2, 2016, Microsoft plans to release the next update of the system, in which you will see new features, as well as get the stability of the system. The build number will be Windows 10 14393. Windows Insider members have already received this build.
Most importantly, you can't get Windows 10 for free now. Unfortunately, the cost of the system is very expensive. So for Windows 10 Core ask-7900, and for Windows 10 Pro-13900. Maybe the prices for the oem version will be lower, I do not own this information.
