Transferring PuTTY session data

Question

My Windows NT account name was changed, and when starting PuTTY it now appears that my saved session information has been lost.

The FAQ suggests that PuTTY sessions should be stored in HKEY_CURRENT_USER\Software\SimonTatham\PuTTY.

Wikipedia explains that HKCU maps to NTUSER.DAT and USRCLASS.DAT under the current user's Desktop and Settings folder.

I still have these files for my old account name, but I'm guessing there is no easy way to extract data from these files?

Answer 1

As described by this Microsoft TechNet article you can load a .dat file into an existing registry:

To load a hive into the registry

1. Open Registry Editor.
2. In the registry tree (on the left), click either the HKEY_USERS or HKEY_LOCAL_MACHINE keys.
3. On the File menu, click Load Hive.
4. In Look in, click the drive, folder, or network computer and folder that contains the hive you want to load.
5. Click Open.
6. In Key Name, type the name that you want to assign to the hive, and then click OK.

You can then browse the tree and export the PuTTY configuration from

HKCU or HKLM\Entered Key Name\Software\SimonTatham\PuTTY

Answer 2

Open your registry files with Direct Registry Browser (freeware), browse your old registry and retrieve your needed keys.
