Tips to export/import putty/Winscp sessions
Exporting your PuTTy saved sessions
1. Click Start->Run and type "RegEdt32" in the "Open" dialog. Click "Ok"
2. Drill into HKEY_CURRENT_USER\Software\SimonTatham
3. Click File->Export. Give your file an appropriate name like, "putty.reg" and click "Save"
4. We're done! Save the putty.reg file somewhere safe. The file doesn't contain any passwords or actual SSH key values so, it's relatively safe from prying eyes. Still, it does contain your configuration and that kind of data is a private matter.
Importing your PuTTy Configuration
1.To import your saved PuTTy configuration on any other Windows computer simply copy your exported registry key, right click on the file and click "Merge
2.Windows will ask you for confirmation that you want to import this set of registry values.
Same for WinSCP sessions:
Drill into “HKEY_CURRENT_USER\Software\Martin Prikryl\WinSCP 2\Sessions” instead
