Here's a simple ".bat" script that allows you to open putty, and connect to a specific server.

START /B putty.exe -ssh [email protected] -pw userpassword

Example:

START /B putty.exe -ssh [email protected] -pw r00tpassw0rd

Note: To work this script has to be stored in ".bat" file, and be located at the same directory as putty, or specify the path to the putty.exe
