By default, the configutil.properties file does not contain registry entries for export. You must manually add the registry path and the entries to the OpenEdge-install-dir/install/configbackup/configutil.properties file as follows:

[HKLM:\Software\PSC\PROGRESS\{version}]
Here are the short forms of the registry hives:
•	HKCR -  HKEY_CLASSES_ROOT. 
•	HKCU -  HKEY_CURRENT_USER.
•	HKLM -  HKEY_LOCAL_MACHINE.
•	HKU  -  HKEY_USERS.
•	HKCC -  HKEY_CURRENT_CONFIG.
•	HKPD -  HKEY_PERFORMANCE_DATA.

How to override a setting the Window’s registry:

As in the above image of the registry entries, if you want to forcibly overwrite WorkPath, which is contained at the level of 12.1 node (node 0) and do not want to overwrite JDKHOME under JAVA node (which is a child node), add the following in the configutil.properties file to set DONT_OVERRIDE or FORCE_OVERRIDE entries: 
[HKCU:\SOFTWARE\PSC\PROGRESS\{version}]
FORCE_OVERRIDE:.WorkPath  
DONT_OVERRIDE:(/JAVA) JDKHOME
