Question

Is there a way to do this?

Or I have to take manually every record from Registry?

Answer 1

Export

cmd.exe, requires elevated prompt due to regedit:

Only sessions (produces file putty-sessions.reg on the Desktop):

regedit /e "%USERPROFILE%\Desktop\putty-sessions.reg" HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions

All settings except ssh keys (produces file putty.reg on the Desktop):

regedit /e "%USERPROFILE%\Desktop\putty.reg" HKEY_CURRENT_USER\Software\SimonTatham

---

Powershell:

Only sessions (produces file putty-sessions.reg on the Desktop):

reg export HKCU\Software\SimonTatham\PuTTY\Sessions ([Environment]::GetFolderPath("Desktop") + "\putty-sessions.reg")

All settings except ssh keys (produces file putty.reg on the Desktop):

reg export HKCU\Software\SimonTatham ([Environment]::GetFolderPath("Desktop") + "\putty.reg")

---

Import

Double-click on the *.reg file and accept the import.

Alternative ways:

cmd.exe, requires elevated command prompt:

regedit /i putty-sessions.reg
regedit /i putty.reg

PowerShell:

reg import putty-sessions.reg
reg import putty.reg

Note: do not replace SimonTatham with your username.

Note: These commands will not export the related SSH keys.
