Backup and restore Putty configuration

1. Click Start->Run and type "regedit" in the "Open" dialog. Click "Ok"

2. Press "Ctrl+F" to bring up the Find dialog. Enter the name of the key, "SimonTatham" in the "Find What" field, and make sure only "Keys" is checked in the "Look At" section of the dialog. Finally, click "Find Next".

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.

5. 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".

Windows will ask you for confirmation that you want to import this set of registry values. We know this file is safe, because we created it but, you should never import registry information from an unknown source.
