An X Window system server for Microsoft Windows
Screenshots
Xming is an X11 display server for Windows operating systems. This piece of free software is secure if you are using SSH as well as an enhanced Plink SSH client. The software is lean, fully-featured, and very simple to install. This is due to it being standalone native Windows that is easy to make portable as it doesn't need machine-specific installation nor any sort of access to a Windows registry. Its interface is similar to that of the Remote Desktop Connection Manager.
Xming can be used with implementations of SSH, which allows you to securely forward X11 sessions from various other computers. You will notice that it supports ssh.exe and PuTTY and comes with PuTTY's plink.exe. You will not need any sort of third-party emulation software such as SmartGaGa because Xming can run natively on Microsoft Windows.
How do I connect to xming server?
After installing Xming onto your Windows device, double click its icon to start the X11 server. You then open the PuTTY session configuration window, and in the window for the PuTTY configuration, you select "Connection --> SSH --> X11."
Ensure that your "Enable X11 forwarding" checkbox is checked. You then go back to the Session category, specify an IP address or hostname, and create a suitable name within the "Saved Sessions." You then save the session.
Is Xming safe?
You will have to mitigate the risk a little because your keyboard and mouse events may be leaked, and things like your clipboard and screenshots may be leaked. Your primary concern should be server security rather than overly worrying about the client.
Rightly popular for its simplicity
This display server software is popular due to its simplicity both in design and how it is implemented. It supports several languages, and it has OpenGL, Mesa 3D, and GLX 3D graphics extensions capabilities.
It is less configurable than Cygwin/X, despite being based on Cygwin/X, the X.Org Server. Nevertheless, it stands shoulder to shoulder with the other free giants in the field and holds its ground well in that it is new-user friendly without dumbing things down for the casual crowd.
