I need to restore Windows 7 power plans. I saved full registry on an old PC (also Windows 7), that PC is not available any more. How can I extract power plans from the saved registry?

Here is what worked for me:

  1. Extract registry branches HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power and ...\ControlSet001\... from the full registry saved--use any text editor
  2. Run regedit, take ownership and change permissions to Full Control for yourself for each of ...\ControlSet00{1|2}\Control\Power branches and all its childs
  3. Import registry branches HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00{1|2}\Control\Power with regedit or reg (failing to do so result in "Cannot import file: ... Error accessing the registry" reported by regedit).
  4. Reboot Windows (failing to do so results in "Your power plan information isn't available" when opening any of power plans)

(Note that ...\CurrentControlSet\Control\Power is filled up automatically with one of ControlSet00X, so you don't need to extract or import it)
