#PuTTY on MS-Windows
Go to the PuTTY download page.
Then download and run the Windows MSI installer putty-0.67-installer.msi
Be warned: if you rather choose to download the stand alone components you will have to do some extra configuration work.
Go to the Xming download page. Then download the Xming installer. Run the installer, accepting all of the defaults as you step through the wizard.
