Download PuTTY: release 0.47

0.47, released on 1999-08-27, is not the latest release. See the Latest Release page for the most up-to-date release (currently 0.70).

Past releases of PuTTY are versions we thought were reasonably likely to work well, at the time they were released. However, later releases will almost always have fixed bugs and/or added new features. If you have a problem with this release, please try the latest release, to see if the problem has already been fixed.
