PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator. PuTTY Tray is an improved version of PuTTY (Win32). It features some cosmetic changes and a number of addons to make it more useful and much more fun to use.

I no longer develop PuTTY Tray, but a number of forks have appeared since the release of a new 'original' PuTTY.
