A MSDN (Microsoft Developer Network) edition

The MSDN software is a software developer-oriented version of Microsoft. MSDN covers all the platforms and applications that can be developed and expanded, such as the Microsoft Encyclopedia Encarta, or a variety of games that are not included in MSDN, because these products are directed toward end users and are not necessary for program development.

MSDN's operating System level is attached to Microsoft's software license, and under MSDN's User License contract (EULA), the software is licensed only to the developer who uses MSDN, for development and testing purposes only, and other people are not allowed to use MSDN attached software.

The packaging is not as exquisite as the retail version, usually with only a piece of CD and instructions (authorization). This system is usually less driven, and the current OEM software is rarely placed on the CD for you to install, either the recovery disk or the hard disk image.

The RTM version of the program code is the same as the official version. But the official version also has a different place: for example, the official version of the OEM can not upgrade the installation, upgrade to a new installation will check the old version of the operating system CD-ROM and so on, these are RTM and the official version of the difference, but their main program code are the same. Strictly speaking, this version still belongs to the FPP Retail edition and needs to be activated.

Four RC (Release Candidate)

From Microsoft's practice, the introduction of the RC version of the operating system on behalf of the official version of the OS is not far away from us, because the development of the Microsoft operating system is such: internal testing->alpha->beta public Test->RC version-> official version of the listing; Typically, Microsoft's RC version filter will go through 2-3 processes, meaning that Microsoft will launch the RC1, RC2 or RC3 operating system, and then the official version of the operating system, so the RC1 version of the operating system is usually the same as the final retail version of the operating system.
