Is there a way to restore a backed up .reg while deleting added keys, not just overwrite existing keys?

  • 772

I want do an export of the current state of the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

And so I can do that with:

reg export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters C:\test.reg /y

What I would like is to perform a restore with that .reg but not just fix/overwrite existing keys, I also need to delete anything that may have been added so that it's a true return to the original state.

Is there a simple way to do this?

Thanks!

    As you only have one key tree, add the following line in the reg file before any other keys:

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters]

    It will delete the top-level key before importing.
