A simple trick login to your server without typing username and password from putty connection.
Right click on the Desktop > New > Shortcut
Browse your putty location, select putty then Click Next
Enter your Server name and Click Finish
Then it will create putty shortcut on your desktop
then you see popup of shortcut property
in the Target: enter username@HOSTIP -pw password
Now Click on OK

Note: Resctrict the file with strict permission not to accessed by other users.
Do not use this option for Critical Production servers, It's always a risky process because your password will be exposed
