How do I import putty connections from an old registry? The old hard drive is USB connected. The option "load hive" is disabled in Regedit. What are my options? Operating system:Windows Seven I got a new HD and installed WIN7 on the new one. The old HD(had WIn7 installed) boots to BSOD. Blue screen of death. The old HD is with me for limited time, so what files related to putty do I need to copy to the new HD?
