PuTTY is tops on the short list of applications I install first on any Windows machine. Over the years I've used PuTTY, I've installed it on a huge number of computers but I've always had one complaint;There isn't a configuration file I can backup or move to a new machine.
Getting all the little comfort settings correct for each SSH connection can be a pain. The third time you set emulation, keys, encryption type, etc. for each machine you regularly access, you lose patience. The fifth time you find yourself re-entering settings you might do what I did, find a better way.
Moving PuTTy settings between computers is an easy task once you know what's involved. We'll find the registry keys where PuTTy stores its configuration information and export them to a file. We'll then use that file we've made to import our configuration on the target machine.
Putty stores its settings in the Windows registry. To save a backup of your Putty settings, you'll need to export this registry key to a file.
