I’m a huge fan of putty – available for download at: Download PuTTY: latest release (0.78) (greenend.org.uk)
Over time, I tend to accumulate a large number of saved “sessions” that I find it useful to either move to a new computer, or save/backup. He
regedit /ea c:\Users\mark\dropbox\_mark\puttycopy.reg HKEY_CURRENT_USER\Software\SimonTatham\PuTTY
Copied that puttycopy.reg to the new drive/computer.
To add the saved sessions, just double clicked on that .reg file on the new computer.
