Install Telnet (client) on Windows 7 (and Windows 2008 Server) From Command Line

Irritatingly Windows 2008 (and Windows 7) doesn't have telnet (client) installed by default.  It can easily be installed with the following command, from the command line (with administrator priveliges):

servermanagercmd -install Telnet-Client

Note: may take "several" minutes to complete.

Of course this can be done through the GUI as well in:

• Control Panel > Programs > Turn Windows features on or off
• In the Windows Features dialog box, select the Telnet Client check box
• Click OK.  Wait. . .
