What is the difference between the Win10 RTM version and the official version?

Many people know the official and preview versions of Win10, and have heard of the Win10 RTM version. But what is the Win10 RTM version? RTM is the meaning of publishing to manufacturing, so what is the difference between Win10 RTM and the official version?
Win10 RTM Edition
The so-called RTM version is the abbreviation of Release to Manufacturing or Release to Marketing. The foreign media industry is accustomed to calling it “Going Gold”. Windows is officially available in retail stores before it takes a while to compress, package, and distribute. Therefore, the program code must be completed some time before the official release. The completed program code is called Final Code. After the program code is developed, The master piece is sent to the factory for a large number of compressions. This version is called the RTM version.
RTM version and official version
Recently, Microsoft revealed to the outside media: Win10 does not have RTM version. So what did we mean by RTM before? Perhaps we have some deviations from Microsoft's understanding, and everyone is still looking forward to the Windows 10 RTM version. Win10 RTM is still a hot word before Microsoft's remarks were released.
According to Microsoft's positioning of Windows 10, this will be the last Windows system, and Win10 will continue to exist as a service, so this system will continue to add new features. From this point of view, Win10 development never stops, so it can not be said that there will be a Win10 RTM version of the traditional functional development.

But we have seen the development and release of Windows systems in the past. After the development to Build 10240, we have entered the traditional RTM milestone, and Microsoft has also distributed this version to OEM partners as a convention. The OEM version of Win10's "raw materials"; and the official retail version of Win10 is also based on this version, after July 29th will be sold in physical stores and online stores, which is in full compliance with RTM's original intention. Therefore, although Win10 RTM does not exist in Microsoft's new theory, as the first release of Win10, Build 10240 does serve as Win10 RTM.

In a word, Win10 RTM in Microsoft's mind should be the end of functional development, but since Win10 will continue to add new features, Win10 RTM does not exist in the traditional sense. Therefore, the release of the official version of Win10 is only the first step of this system "the long march", there should be a long way to go in the future.
From the above information, we can understand that there is no RTM in win10. This is just a vocabulary that has been left in the past. The official version of win10 has been released, please update it in time.
The above is the difference between the Win10 RTM version and the official version. It can be said that the Win10 RTM version is only a temporary version, and the official Win10 version will be replaced.
