Microsoft offers Desktop and Server versions of Windows operating system

At first glance Windows (Desktop) and Windows Server look similar, but each has different uses.
Both are based on the (windows) NT kernel family with the Desktop versions being locked down in various ways to discourage their use as a Server.
Also the Windows Server is locked down in certain functionalities depending on the license.

OpenSource Software ported to Windows: MinGW64

MinGW is a minimalist development environment for native Microsoft Windows applications. Mingw-w64 is an advancement of the original project, created to support the GCC compiler on Windows. MinGW compilers provide access to the functionality of the Microsoft C runtime and some language-specific runtimes. MinGW, being Minimalist, does not, and never will, attempt to provide a POSIX runtime environment for POSIX application deployment on MS-Windows. If you want POSIX application deployment on this platform, you can consider Cygwin instead.
