+# Connecting from a Windows Client
+
+## SSH with PuTTY without X11 Forwarding
+
+PuTTY is one of the most common tools for SSH.
+
+Check, if the following software packages are installed on the Windows workstation by 
+inspecting the *Start* menu (hint: use the *Search* box to save time):
+* PuTTY (should be already installed)
+* *[Optional]* Xming (needed for [SSH with X11 Forwarding](#ssh-with-putty-with-x11-forwarding))
+
+If they are missing, you can install them using the Software Kiosk icon on the Desktop.
+
+1. Start PuTTY
+
+2. *[Optional]* Enable ``xterm`` to have similar mouse behavour as in Linux:
+
+   ![Enable 'xterm'](../../images/PuTTY/Putty_Mouse_XTerm.png)
+
+3. Create session to a Merlin login node and *Open*:
+
+   ![Create Merlin Session](../../images/PuTTY/Putty_Session.png)
+
+
+## SSH with PuTTY with X11 Forwarding
+
+Official X11 Forwarding support is through NoMachine. Please follow the document
+[{Job Submission -> Interactive Jobs}](../03-Slurm-General-Documentation/interactive-jobs.md#requirements) and
+[{Accessing Merlin -> NoMachine}](../02-How-To-Use-Merlin/nomachine.md) for more details. However,
+we provide a small recipe for enabling X11 Forwarding in Windows.
+
+Check, if the **Xming** is installed on the Windows workstation by inspecting the 
+*Start* menu (hint: use the *Search* box to save time). If missing, you can install it by
+using the Software Kiosk icon (should be located on the Desktop). 
+
+1. Ensure that a X server (**Xming**) is running. Otherwise, start it.
+
+2. Enable X11 Forwarding in your SSH client. In example, for Putty:
+
+   ![Enable X11 Forwarding in Putty](../../images/PuTTY/Putty_X11_Forwarding.png)
