How to backup PuTTY Settings
PuTTY is a very lightweight SSH Client software for the Windows Operating system. Sometimes you need to back up and restore Putty sessions (saved SSH connections) to another computer. Putty stores its settings and SSH sessions in Windows Registry.
PuTTY settings are stored in Windows Registry at
HKEY_CURRENT_USER\Software\SimonTatham
To back up, the settings, run
regedit /e "%USERPROFILE%\Desktop\putty.reg" HKEY_CURRENT_USER\Software\SimonTatham
This will create a file putty.reg on your Desktop.
To restore it, double click on the putty.reg file.
