You can back up your PuTTY session profiles or the entire configuration using the Windows Registry Editor.
✅ Export Only PuTTY Sessions
To export only saved sessions:
regedit /e "%userprofile%\Desktop\putty-sessions.reg" HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions
This will save a file called putty-sessions.reg
to your desktop containing all your session configurations.
✅ Export All PuTTY Settings
To back up all PuTTY settings, including sessions and preferences:
regedit /e "%userprofile%\Desktop\putty.reg" HKEY_CURRENT_USER\Software\SimonTatham
This creates putty.reg
on your desktop with the full configuration data.
🔄 To Restore PuTTY Settings
Double-click the exported .reg
file and confirm when prompted to import it back into the registry.
