Windows Registry has many limitations on editing Registry Keys. Some keys are “owned” by the system or “TrustedIstaller” service and users that are Administrators cannot edit these keys.
This tool can reset registry key permissions and allow you to modify or even remove registry keys and values within.
Run BeRegOwner and add the registry key that you need to have access.
Click “Take Ownership” Button
Now you can access and modify that registry key.
