Xming is a Free Software port of the X Window Server to Microsoft Windows. It shares the same source code base as Cygwin/X but does not depend on the Cygwin environment or cygwin1.dll. Xming is a fully featured X Window Server for Microsoft Windows that is very simple to install and use.
Xming is made from Xorg (X11R6.9), and a patch bundle, cross-compiled with MinGW and Pthreads-Win32.
