Putty stores known hosts under a registry key: HKEY_CURRENT_USER\SoftWare\SimonTatham\PuTTY\SshHostKeys.

You should accept this answer, because it's totally correct –  A. Wilson Oct 11 '13 at 13:02

Just as a side note, if you want to export the registry keys to a known_hosts file, there is a nice tool for this.
