Excellent little configuration guide here, I seemed to have missed configuring PuTTY all together, but now I have it set up nice thanks to you.

Also thanks to the other commentors mentioning:

• PuTTY CM | http://puttycm.free.fr
• PuTTY Tray | http://www.xs4all.nl/~whaa/putty/

and

• portaPuTTY | http://code.google.com/p/portaputty/

there is also another portable putty from portableapps.com:

• PuTTY Portable | http://portableapps.com/apps/internet/putty_portable

Tip: Also if you like to go full screen with Alt+Enter (like cmd box on Windows), when configuring the default profile make sure to select/tick - Category: Window, Behaviour, Full screen on Alt+Enter :)
