Question: where are putty settings saved?
Answer: PuTTY settings are shared in HKEY_CURRENT_USER in the registry, so you can export these to a file for use elsewhere. To export, run RegEdit.exe and navigate to HKEY_CURRENT_USER\Software\SimonTatham\PuTTY. Right click on the PuTTY entry in the tree and select Export. Save this file to your thumb drive or H: drive.
