I wanted to do a quick backup of my running config without needing to setup a TFTP server.
You will first want to get to enabled mode

router# terminal length 0
The next step is configuring your putty session as follows:
Right-click the window title and choose ‘Change Settings’

Select the ‘All session output’ radio button and choose a destination file
Now send a ‘show running-config’ command and the config will be sent to your log file.
router# sh run
