Windows

The Goal: Instead of using the Windows command line, use a Putty terminal that connects passwordlessly to an sshd server running on localhost.

Anybody who has used ssh on Linux for any period of time has probably done something like this to allow passwordless logins between systems. The concept is pretty much the same, but the tools are different. By the way, these instructions are for XP, and I have no idea whether they would work with Vista.
