If you select and expand the Hive you’ve just loaded, you will notice that there is no CurrentControlSet Node. You will only see CurrentControlSet001 and . To know which one is active, you need to click on the “Select” key (under the loaded hive) and check the value stored in the Current DWORD entry.
If the value is 1, you need to update CurrentControlSet001
If the value is 2, you need to update CurrentControlSet002
